Question

what is the acceleration due to gravity on a planet with a mass 10 times that of earth, and a diameter 4 times that of earth

Answer 1

gravity is changed by a factor of 10/16

Step-by-step explanation:

gravitational force = m1 m2 G / r^2 now change the m1 and r

= 10 m1 m2 G/ (4 r)^2

= 10 /16 m1 m2 G / r^2

10 /16 the earth's gravity
