A -11 nC charge is located at (x, y) = (0.80 cm , 0 cm).

Part A:

What is thex-component of the electric field at the position

(x,y) = (4.4 cm , 0 cm)?

Part B:

What is the y-component of the electric field at the

position (x, y) = (4.4 cm , 0 cm)?

Part C:

What is thex-component of the electric field at the position

(x,y) = (4.4cm, 0 cm)?

Part D:

What is the y-component of the electric field at the

position (x, y) = (4.4cm, 0 cm)?

Part E:

What is thex-component of the electric field at the position

(x,y) = (0 cm, 4.4 cm )?

Part F:

What is they-component of the electric field at the position

(x,y) = (0 cm, 4.4 cm )?

Parts A-D I got correct, E and F are what I need help with.

Answers to A-D

A: -7.6x10^4 N/C

B: 0 N/C

C: 3.7x10^4 N/C

Solution

The point (x1,y1)=(0 cm, 4.4 cm)

charge is located at (x, y) = (0.80 cm , 0 cm).

let x0=0.8

let y0=4.4

Electric field(E)= k*q/r^2

q=-11nc

r= sqrt(x0^2 + y0^2)

Electric field at (0 cm, 4.4 cm) (E)= kq/r^2

But this this electric field is towards the charge. SO we

have to make it into two components(x and y components)

x component = E * sin(t)

y component = -E * cos(t)

sin(t) = x0/r

cos(t) = y0/r

E)x-component of the electric field at (0 cm, 4.4 cm)=

k*q*x0/r^3

F)y-component of the electric field at (0 cm, 4.4 cm)= -

k*q*y0/r^3

Note : I hope you can do the calculations.

Have a nice day.

Economic Order quantity EOQ

1. Northwest Hospital currently buys surgical gloves in lots of 1,500 boxes once every four months. Under this ordering policy, demand for gloves will be completely satisfied with no surplus and no shortage. The carrying cost is $15.00 per box per year, which is equivalent to 10% of the cost per box. The ordering cost is $150 per order. What is the cost of one box of gloves? 2. Under the current ordering policy (i.e., 1,500 boxes every four months), what is the annual total inventory holding cost? 3.

Outsourcing Srategy

1. Clearly define the scope and schedule for your project Define your project requirements up front. Service providers need accurate, complete information to present you with realistic proposals and to quote you a good fixed price deal. Give vendors as much information as you can about what you need delivered and the way in which you need the work done. Also, be clear and realistic about your schedule requirements - project schedules can have a huge impact on project costs.

Economic Order quantity EOQ, Economic Production Quantiry EPQ

Objective 309.3.1-06: Determine order size using the economic order quantity model. Objective 309.3.1-07: Determine lot size using the economic production lot size model. A variety of criteria and techniques can be used to determine how many units of a product to purchase or produce and what parameters to set for inventory management. In this task, apply the economic order quantity model and the economic production lot model to related decisions. Given: Company A’s demand is uniform throughout the year and totals 18,000 units per year. Ordering costs total $38 per order. The annual holding cost rate is 26% of the value of the inventory. The per-unit cost of inventory is $12. Company B’s demand is uniform throughout the year and totals 15,000 units per year. The production setup costs total $84 per setup. The annual holding cost rate is 28% of the value of the inventory. The per-unit cost of finished product is $19. The production rate is constant and equivalent to 60,000 units per y

Linear Programming

Coffee Beans Mrs. Olsen, a coffee processor, markets three blends of coffee. They are; Brand X , Minim and Taster's Reject. Olsen uses two types of coffee beans to make the three different brands; Columbian and Mexican Beans. The following chart list the composition of the blends: Brand Percentage of Columbian Beans Percentage of Mexican Beans Brand X 80% 20% Minim 50% 50% Tasters Reject 30% 70% Ms. Olsen has already purchased 20,000 pounds of Columbian beans at 90 cents per pound, and she has purchased 30,000 pounds of Mexican beans at 50 cents per pound. At such, these resources are available for use. Unused Columbian beans can be sold at cost to another processor, but unused Mexican beans can be sold only for 35 cents per pound. Due to warehouse space limitations, Ms. Olsen must dispose of all unused beans.

Net Present Value

Having heard of your knowledge of present value techniques, you have been asked to testify as an expert witness in the following lawsuit. Several homeowners in a nearby community have organized to protest against alleged gouging on the part of a local lending institution. One resident presents his payment book as evidence. The resident has a 30-year, fixed rate loan at 6 percent interest for $200,000. He got the loan 10 years ago and has been making equal annual payments of $14,529.60 ever since. He observes that he has paid the lending company $145,296.00 yet his payment book indicates that the principal due on the loan has only declined by $33,345.40. He presents this as obvious proof of "gouging on the part of the money changers". Required: Do you agree? Why, why not? (Support your answer with any relevant calculations.)
