Question

A cylinder of weight w is resting on a fixed V-groove as shown in figure. Calculate normal reactions between the cylinder and two inclined walls.

• A. w, w
• B. $w/2,w/2$
• C. $w,w/2$
• D. $w/2.w$

Answer 1

The correct option is A w, w

Let $N$ is the normal acting on the cylinder by the wall is

So, on balancing force,

$2N\cos \theta =mg$

Since ball is symmetrically placed. Normal reaction by both wall will be same.
