Physics - Gravitation Question with Solution | TestHub

A spherical uniform planet is rotating about its axis. The velocity of a point on its equator is$V$. Due to the rotation of the planet about its axis the acceleration due to gravity$g$at equator is$\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.$of$g$at poles. The escape velocity of a particle on the planet in terms of$V$from the pole of the planet is
