Two weights A and B weighing 7 kg and 3 kg, respectively, are hanging

1.	Two weights A and B weighing 7 kg and 3 kg, respectively, are hanging on each end of a frictionless pulley fixed on theceiling, as shown in the above diagram. As a force of FF is beingapplied to weight B,the weights stay in equilibrium. Find themagnitude of F. Assume that gravitational acceleration is g=10 m/s2.
Answer» ANSWER: the FORCE at both ends MUST be balanced that is 70N=F+30N so F=40N hope it helps please mark me as the BRAINLIEST.

ANSWER:

the FORCE at both ends MUST be balanced

that is 70N=F+30N

so F=40N
