Weight of a body is maximum at

A man can jump to a height of $1.5 \,m$ on a planet $A$. What is the height he may be able to jump on another planet whose density and radius are, respectively, one-quarter and one-third that of planet $A$ .......  $m$

At what height above the earth’s surface does the acceleration due to gravity fall to $1\%$ of its value at the earth’s surface ?

A body weight $ W $ newton at the surface of the earth. Its weight at a height equal to half the radius of the earth will be

A certain planet completes one rotation about its axis in time $T$. The weight of an object placed at the equator on the planet's surface is a fraction $f(f$ is close to unity) of its weight recorded at a latitude of $60^{\circ}$. The density of the planet (assumed to be a uniform perfect sphere) is given by

If $R$ is the radius of the earth and the acceleration due to gravity on the surface of earth is $g=\pi^2 \mathrm{~m} / \mathrm{s}^2$, then the length of the second's pendulum at a height $h=2 R$ from the surface of earth will be,:
