Question

our planet has three times the mass of the earth and two times the radius of the earth calculate the value of acceleration due to gravity on the surface of the plane​

Answer 1

Answer:

3/4 g

Explanation:

g=GM/R^2

M' = 3M

R' = 2R

g' = GM'/R'^2

= G (3M)/(2R)^2

= 3/4 GM/R^2

= 3/4 g

Answer 2

Answer:

q ′= GM/R²

= G×2me/(4ve²)

= 1 Gme/8 ve²

= g/8

To find 4 times the acceleration due to gravity =4×⅛g = 8/2=g/2 = 10/2

= 5m/s²

Hence, the answer is 5m/s² .
