The escape velocity of a body depends upon mass as

A cylinder of height $20 \mathrm{~m}$ is completely filled with water. The velocity of efflux of water (in $\mathrm{ms}^{-1}$ ) through a small hole on the side wall of the cylinder near its bottom is

Speeds of two identical cars are $u$ and $4 u$ at the specific instant. The ratio of the respective distances in which the two cars are stopped from that instant is

If suddenly the gravitational force of attraction between Earth and a satellite revolving around it becomes zero, then the satellite will

A light string passing over a smooth light pulley connects two blocks of masses $m_1$ and $m_2$ (vertically). If the acceleration of the system is $\mathrm{g} / 8$, then the ratio of the masses is
