Answer:
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
