BITSAT PYQs for Escape Speed with Solutions

1.
The escape velocity from the surface of a planet is 11.2 km/s. If the radius of the planet is doubled but the mass remains the same, what will be the new escape velocity?
- 22.4 km/s
- 7.9 km/s
- 15.8 km/s
- 5.6 km/s

2.
There are two planets. The ratio of radius of the two planets is $k$ but ratio of acceleration due to gravity of both planets is g. What will be the ratio of their escape velocity?
- $(Kg)^{1/2}$
- $(Kg)^{ - 1/2}$
- $(Kg)^{2}$
- $(Kg)^{ - 2}$

3.
An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth. The height $(h)$ of the satellite above the earth?s surface is (Take radius of earth as $R_e$)
- $h = R^2_e$
- $h = R_{e}$
- $h = 2R_e$
- $h = 4R_e$

4.
The acceleration due to gravity on the surface of the moon is $1/6$ that on the surface of earth and the diameter of the moon is one-fourth that of earth. The ratio of escape velocities on earth and moon will be
- $\frac {\sqrt {6}} {2}$
- $\frac{1}{\sqrt{24}}$
- $3$
- $\frac {\sqrt {3}}{2}$
