Question

A point $A$ on a sphere of weight $W$ rests in contact with a smooth vertical wall and is supported by a string joining a point $B$ on the sphere to a point $C$ on the wall. Draw a free body diagram of the sphere.

Answer 1

Weight $\left(W\right)$ of the sphere acts in the downward direction, rope exerts a tension force $\left(T\right)$ along its length and the wall exerts a normal force $\left(N\right)$ on the sphere as shown in the figure.
