A planet has 20% mass More than earthand radius less than 20% so what the acceleration due to gravity of that planet​

Answer»

Answer:

GRAVITY DEPEND on M/R^2

let MASS is m and RADIUS is r

then

planet has mass of 6m/5

and radius is 4r/5

acc. DUE to gravity is (6m×25)/(5×16r^2)

=30GM/16r^2

=15GM/8R^2

it is 15g/8

ok
