List of top Physics Questions on Escape Speed asked in AIIMS

Taking the radius of the earth to be $6400 \,km$, by what percentage will the acceleration due to gravity at a height of $100\, km$ from the surface of the earth differ from that on the surface of the earth?

A rocket is fired upward from the earth surface such that it creates an acceleration of $19.6\, m / s ^{2}$. If after $5\, s$, its engine is switched off, the maximum height of the rocket from earth's surface would be

The velocity with which a projectile must be fired so that it escapes earth's gravitation does not depend on

Escape velocity of a rocket is $11.2\, km/sec$. It is released at an angle of $45^{\circ}$. Its escape velocity is
