List of top Physics Questions on Gravitation asked in LPUNEST

The centre of mass of a rigid body lies:
If gravitational acceleration at surface is \(g\), increase in P.E. lifting mass \(m\) to height equal to half radius \(R/2\) from surface will be
The mass of a spaceship is \(1000\,\text{kg}\). It is to be launched from the earth's surface out into free space. The value of \(g\) and \(R\) (radius of earth) are \(10\,\text{m s}^{-2}\) and \(6400\,\text{km}\) respectively. The required energy of this spaceship will be:
A particle executing SHM along a straight line has zero velocity at points $A$ and $B$ whose distances from $O$ on the same direction $OAB$ are $a$ and $b$ respectively. If the velocity at the midpoint between $A$ and $B$ is $v$, then its time period is
