List of top Physics Questions on Gravitation asked in AMUEEE

Three particles, two with masses $m$ and one with mass $M$ , might be arranged in any of the four configurations shown below. Rank the configurations according to the magnitude of the gravitational force on $M$ , least to greatest

A small satellite is in elliptical orbit around the earth as shown in figure. $L$ denotes the magnitude of its angular momentum and $K$ denotes its kinetic energy. If $1$ and $2$ denote two positions of the satellite, then

The density of a newly discovered planet is twice that of earth. The acceleration due to gravity at the surface of the planet is equal to that at the surface of the earth. If the radius of the earth is $R$, the radius of the planet would be

A rocket is launched vertically upward from the surface of the earth with an initial velocity of $10 \,km/s$ . If the radius of the earth is $6400 \,km$ and atmospheric resistance is negligible. Find the distance above the surface of the earth that the rocket will go.

Which of the following curves represents the variation of total energy with radius r for a satellite in a circular orbit?

Calculate the acceleration due to gravity on the surface of a pulsar of mass $M = 1.98 \times 10^{30}\, kg$ and radius $R = 12 \,km$ rotating with time period $T = 0.041 \,s. (G = 6.67 \times 10^{-11}MKS)$

If a graph is plotted between $T^2$ and $r^3$ for a planet, then its slope will be (where $M_S$ is the mass of the sun)

An artificial satellite moving in a circular orbit at a distance $h$ from the centre of the earth has a total energy $E_0$. Its potential energy is

Two satellites are moving in the same circular orbit around the earth. They must have the same
