The range of a projectile of weight $W$ is $R$. The average torque on the projectile between the initial and final positions $\mathrm{P}$ and $\mathrm{Q}$ about the point of projection is
$\frac{W R}{2}$
$\frac{W R}{3}$
$\frac{W R}{4}$
WR
Solution
Given, range of a projectile of weight $W=R$
The average torque on the projectile between the initial and final positions $\mathrm{P}$ and $\mathrm{Q}$ about the point of projection,
$
\mathrm{T}=\frac{\mathrm{WR}}{2}
$
