AIPMT 2005 | Gravitation Question 52 | Physics

AIPMT 2005

MCQ (Single Correct Answer)

-1

Imagine a new planet having the same density as that of earth but it is 3 times bigger than the earth in size. If the acceleration due to gravity on the surface of earth is g and that on the surface of the new planet is g', then

g' = g/9

g' = 27g

g' = 9g

g' = 3g
