Question

Two weights A and B weighing 7 kg and 3 kg, respectively, are hanging on each end of a frictionless pulley fixed on the

ceiling, as shown in the above diagram. As a force of FF is being

applied to weight B,the weights stay in equilibrium. Find the

magnitude of F. Assume that gravitational acceleration is g=10 m/s

2.

​

Answer 1

Answer:

the force at both ends must be balanced

that is 70N=F+30N

so F=40N
