List of top Physics Questions on Gravitation asked in AP EAMCET

The time period of revolution of a satellite close to the planet’s surface is 80 minutes. The time period of another satellite which is at a height of 3 times the radius of the planet from the surface is:
The gravitational field due to a mass distribution is \( E = \frac{K}{x^3} \) along x-direction (K is a constant). Taking the gravitational potential to be zero at infinity, its value at a distance \( x \) is:
Two satellites of masses \( m \) and \( 1.5m \) are revolving around the Earth with different speeds in two circular orbits of heights \( R_E \) and \( 2R_E \) respectively, where \( R_E \) is the radius of the Earth. The ratio of the minimum and maximum gravitational forces on the Earth due to the two satellites is
Maximum height reached by a rocket fired with a speed equal to 50\% of the escape speed from the surface of the earth is (R – Radius of the earth)

The value of acceleration due to gravity g is maximum at?

A projectile is thrown straight upward from the earth's surface with an initial speed \(V=\alpha V_E\), where \(\alpha\) is a constant and \(V_E\) is the escape speed. The projectile travels upto a height \(800 \, km\) from earth's surface before it comes to rest. The value of the constant \(\alpha\) is
\[ (\text{Radius of the earth} = 6400 \, km) \]
