Given
Weight of object : 10N
Mass of planet P : Me/10
Radius of planet P : Re/2
Since we know that
F =
Then , gravitational force on planet P
F' =
Mp = Me/10
Rp = Re/2
Putting the values
F' = (G Me/10 . m) / (Re/2)^2
Simplifying the above eqn. , we get
F' =
and
F' = F
F' = * 10
F' = 4N
Therefore , weight of the body on planet P = 4N
