A rod of weight $\displaystyle W$ is supported by two parallel knife edges A and B and is in equilibrium in a horizontal position. The knives are at a distance $\displaystyle d$ from each other. The centre of mass of the rod is at distance $\displaystyle x$ from A. The normal reaction on A is :
Official answer
(4)
$\displaystyle \frac{W(d-x)}{d}$
