A spherical uniform planet is rotating about its axis. The velocity of a point on its equator is 7.5 kms^(-1) . Due to the rotation of the planet about its axis, the acceleration due to gravity g at equator is 1//2 of g at poles. What is the escape velocity ("in km s"^(-1)) of a particle on the planet from the pole of the planet?

A uniform spherical planet is rotating about its axis. The speed of a point on its equator is v and the effective acceleration due to gravity on the equator is one third its value at the poles. Calculate the escape velocity for a particle at the pole of the planet. Give your answer in multiple of v.

The earth rotates about its own axis, then the value of acceleration due to gravity is

If the earth stops rotating about its axis, then acceleration due to gravity remains unchanged at

Consider a spherical planet rotating about its axis. The velocity of a point at equator is v. The angular velocity of this planet is such that it makes apparent value of ‘g’ at the equator half of value of ‘g’ at the pole. The escape speed for a polar particle on the planet expressed as multiple of v is :
