The systems shown below are in equilibrium (with m = 3.50 kg and θ = 32.0°). If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline are frictionless.
scale in (a) N
scale in (b) N
scale in (c) N
scale in (d) N
Thank you for the opportunity to help you with your question!
Dear student, please attach the photo in the reply box so that I can see it and help you. just attach it below this message.
weight= 3.5kg *10= 35 N
c) (3.50+3.50)kg*10=7*10=70 N
d) sin θ=10/N
I hope that will help. Remember gravity is assumed to be 9.8N~10N
