The escape velocity of an object projected from the surface of a given planet is independent of

A

radius of the planet

B

the direction of projection

C

the mass of the planet

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

The escape velocity of an object from any planet is
`v_("escape") = sqrt(2gR) = sqrt(2GM//R)`
Where R & M are the radius & mass of the planet.
