A. Explore
How do you define electrical
charge based on the image?
No need to submit
your answers. We will
answer the question as
we proceed with our
lesson.
General Physics 2 discusses the various concepts of physics and their real-life applications. This
subject will guide you in appreciating the role of Physics in your daily life. Your understanding of
these concepts will be accompanied and reinforced with several exercises and online activities. For
the first unit, you will learn how Electricity and magnetism work hand-in hand in making different
kinds of equipment. Then the knowledge you learned here will be further expounded as you study
electromagnetic induction, optics, relativity, and radioactivity in unit 2. This subject will hopefully
inspire you to pursue a career in Physics.

General Physics 2 Performance Task
GOAL
To inspire others and show everyone that you are a deserving DOST Scholar.
ROLE
A DOST Scholar Student
AUDIENCE
Community, Schoolmates and Teachers
SITUATION
You are a DOST Scholar. As one of the requirements for being a DOST Scholar is for you
to join the annual celebration of your scholarship program celebrated through a contest
of solving problems. This year, the problems to be solved deals with the concept of
Electricity and Magnetism. Problems will be given to all of you and then using theoretical
and experimental approaches, you are going to solve the problems prepared. Being one
of the scholars, you are going to join the competition.
Compute the charge of the following ions.
1. Anion with a charge of -3
2. Cation with a charge of +2
3. Anion with a charge of +5
Determine the charge of each atom if it is composed of the following particles:
1. 5 electrons and 5 protons
2. 6 protons and 5 electrons
Determine the resulting charges of each material in the following pairs if they are rubbed together.
1. Wool and Human Hair
2. Dry hand and Polyester
Illustrate how charging by conduction happens when a strong positive body A is brought near an
electrically neutral body B. Be guided by the statements provided in each box. Label your illustrations
clearly.
1. An electrically neutral body B and a strongly positive body A are separated by distance y.
2. Body B is brought near body A up to a distance x. Note that x is not equal to zero.

PRODUCT
A complete solution written presentably of the problem solving below:
1. There are two steel balls both weighing 0.75 kg and carrying and carrying equal
but opposite charges. Find their individual charges if the force of attraction
between them is 5.11 n and if they are separated by a distance of 1.11 m.
2. A square has an area of 9 cm
2.
At one vertex of the square is a +3 uC charge,
and opposite it is another +3 uC charge. At the other free vertex, a charge of -3
uC can be found. Suppose a +3 uC charge will be placed at the last vertex of
the square, how much electrostatic force will it experience?
3. Compute the electrostatic force experienced by +4.43x10
-18
C charge from a
9.56 x 10
16
N/C electric field
4. Find the repulsive force between the nucleus of a helium atom with charge of
+2e and that of a neon atom with charge of +10e when they are 3 nm apart
from each other. Consider the nuclei are in vacuum, and e=1.60x10
-19
C.
5. In lightning bolt, 16 C of charge flows for 1.7x10-3 s. Assuming that the
lightning bolt is a long, straight line of current, what is the magnitude of the
magnetic field at a distance of 30 m from the bolt?
