Question

# Find magnitude of force exerted by string on the pulley.

A
100 N
B
1002 N
C
200 N
D
100 N

Solution

## The correct option is C $$100 \sqrt 2\ N$$F.E.D. if 10 kg block:T = 10 g = 100 NF.B.D. of pulley :Since is mass less, so tension both sides of string is same.Force exerted by string then is= $$\sqrt{(100)^2\,+\, (100)^2}\,=\, 100\sqrt{2}\, N$$Physics
