a metal sphere is hung by a string o a wall. the sphere is pushed away from the wall by a stick. The force from the stick acts horizontally. which of the following is wrong? ( P= force by the stick, w = weight of sphre , t= tension force by string)

a. P = W tan theta

b. T + P + W = 0

c.T squared = P squared + W squared

d. T = P + W

Dear Goutham,

Option d i.e. T=P+W is incorrect Since the direction of P, W and T are opposite thats why this relation cannot hold .

Best Of luck
