The amplitudes of a damped harmonic oscillator after 2 and 4 seconds are $A_1$ and $A_2$ respectively. If the initial amplitude of the oscillator is $A_0$, then

The range of a projectile of weight $w$ is $R$. The average torque on the projectile between the initial and final positions $P$ and $Q$ about the point of projection is

Among the following the least unit for length is

Two vectors of same magnitude act at a point. Twice the product of the magnitudes of two vectors is equal to the square of the magnitude of their resultant. The angle between the two vectors is

The property of light which cannot be explained by Huygen's construction of wavefront is
