A small sphere is hung by a string fixed to a wall. The sphere is pushed away from the wall by a stick. The forces acting on the sphere are shown in figure. Which of the following statements is wrong ? 2 blocks A and B of weight 10 kg and 5 kg respectively are placed on a smooth inclined plane as shown. The system is in equilibrium. If the angle of inclination is increased, the block B starts slipping.

A

`P = W tan theta`

B

`vec(T) + vec(P) + vec(W) = 0`

C

`T^(2) = P^(2) + W^(2)`

D

T = P + W
