The apparent weight of a person inside a lift is $ w_{1}$ when lift moves up with a certain acceleration and is $ w_{2}$ when lift moves down with same acceleration. The weight of the person when lift moves up with constant speed is

If force $ (F) $ , work $ (W) $ and velocity $ (V) $ are taken as fundamental quantities, then the dimensional formula of time $ (T) $ is

In Ramsden eye-piece the focal length of each lens is $F$ . The distance of the image formed by the objective lens from the eye lens is

A body is thrown vertically up with certain initial velocity. The potential and kinetic energies of the body are equal at a point $P$ in its path. If the same body is thrown with double the velocity upwards, the ratio of potential and kinetic energies of the body when it crosses the same point, is

The source is at some distance from an obstacle. Distance between obstacle and the point of observation is $b$ and wavelength of light is $\lambda$. Then the average distance of nth Fresnel zone will be at a distance from the point of observation
