List of top Physics Questions on Gravitation asked in JIPMER

At what height above the earth?s surface, the value of $g$ is half of its value on earth?s surface? Given its radius is 6400 km.
A projectile is fired vertically upwards from the surface of the Earth with a velocity $k\upsilon _e$ , where $\upsilon_e$ is the escape velocity and $k < 1$ . If $R$ is the radius of the Earth, the maximum height to which it will rise measured from the centre of the Earth will be

Kepler's second law is a consequence of

If a planet has twice the mass of earth and three times the radius $(R)$ of earth, then the escape velocity of the planet is ($\upsilon_e$ = escape velocity of earth)
Two satellites $A$ and $B$ go round a planet $P$ in circular orbits having radii $4R$ and $R$ respectively. If the speed of the satellite $A$ is $3\upsilon$, the speed of satellite $B$ will be
A planet in a distant solar system is 10 times more massive than the earth and its radius is 10 times smaller. Given that the escape velocity from the earth is ${11 \, km \, s^{-1}}$, the escape velocity from the surface of the planet would be
The speed of earth?s rotation about its axis is $\omega$. Its speed is increased to $x$ times to make the effective acceleration due to gravity equal to zero at the equator. Then $x$ is
Two identical satellites $A$ and $B$ revolve around the earth in circular orbits at distance $R$ and $3R$ from the surface of the earth. The ratio of the linear momenta of $A$ and $B$ is ($R$ = radius of the earth)
For a satellite moving in an orbit around the earth, the ratio of kinetic energy to potential energy is
Imagine a new planet having the same density as that of earth but it is $3$ times bigger than the earth in size. If the acceleration due to gravity on the surface of earth is g and that on the surface of the new planet is g, then
Earth is revolving around the sun. If the distance of the earth from the sun is reduced to $1/4th$ of the present distance then the length of present day will be reduced by:
Two planets are revolving around the earth with velocities $v_{1}$ and $v_{2}$ and in radii $r_{1}$ and $r_{2}$ $\left(r_{1} > r_{2}\right)$ respectively. Then :
The escape velocity for the earth is $11.2 \,km / sec$. The mass of another planet $100$ times mass of earth and its radius is $4$ times radius of the earth. The escape velocity for the planet is:
A small satellite is revolving near earths surface. Its orbital velocity will be nearly:
The maximum and minimum distance of a comet from the sun are $ 8\times 10^{12}m$ and $ 1.6\times 10^{12}m$ . If its velocity when nearest to the sun is 60 m/s, what will be its velocity in m/s when farthest?
A artificial satellite is going round the earth assumed to be uniform sphere. Its period t will depend on the density $ \rho $ by the relation (k is numerical constant)
