The escape velocity from the surface of the earth is ve.The escape velocity from the surface of a planet whose mass and radius are three times those of the earth, will be

1. v_e
2. 3v_e
3. 9v_e
4. 1/ 3v_e

Correct Option: A

Escape velocity on surface of earth

(v_e) = √	2GM_e	∝ √	M_e
	R_e		R_e

or, v_P= v_e.
