List of top Physics Questions on Gravitation asked in BITSAT

The escape velocity from the surface of a planet is \(v_e\). What will be the escape velocity from a planet whose mass and radius are twice that of the original planet?
What is the dimension of the Gravitational constant?
Conversation of linear momentum is a necessary condition for which Kepler's laws?
If an object of mass m is given a velocity equal to twice the escape velocity of Earth then the velocity of the object at the point where Earth shows no Gravitational force strength would be at?
The time period of a satellite of earth is $5$ hours. If the separation between the earth and the satellite is increased to $4$ times the previous value, the new time period will become
There is a shell of mass $M$ and density of the shell is uniform. The work done to take a point mass from point $A$ to $B$ is $[A B=r]$
The force constant of a spring gun is $50 \,N / m$. If a ball of $20 \,g$ be shoot by the gun, so that its spring is compressed by $10 \,cm$, the velocity of the ball is:
If density of earth increases $4$ times and its radius becomes half of what it is, our weight will
