Anew planet is discovered that has twice the earth's mass and twice the earth's radius. on the surface of this new planet a person who weights 500 n on earth would experience a gravitational force of

(a) 125 n
(b) 250 n
(c) 500 n
(d)) 1000 n
(e) 2000 n

option B

Explanation:

Radius of new planet,R' = 2R

Mass of the earth, M' = 2 M

R and M is the Radius and Mass of the earth.

Weight of the person on earth = 500 N

Weight of the person in the new planet = ?

We know acceleration due to gravity is calculated by using formula

now, acceleration due to gravity on the new planet

here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.

Weight on the new plane is equal to = 250 N

correct answer is option B
