Question

In the diagram 100 kg block is hanging from a pulley and force F is applied on the string to keep the system in equilibrium. If tire whole system is moving up with a constant velocity v, then tension at point P in the string will be

(a) 735 N

(b) 1050 N

(c) 1470 N

(d) 1200 N

Answer 1

Correct option (c) 1470 N

Explanation :

Tension in each part of the string wilt be F. Assume tension at point P ts T.
