PhysicsNEET 2021Kepler's laws, satellites, escape velocity

Gravitation

The escape velocity from the Earth's surface is $v$ . The escape velocity from the surface of another planet having a radius four times that of Earth and the same mass density is:

A. $v$
B. $2 v$
C. $3 v$
D. $4 v$ ✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
