please it is very urgent ..exam

Dear Student

On Any planet Gravitation g=Gm/r² 

(Where G=Universal Gravitational constant, m= Mass of the planet, R= Radius of the planet)

Sub stitute m=M/2, r=R/2    (M,R are Mass and radius of earth )

gravitation on tha planet =(GM/2)/(R²/4)= 2GM/R²=2g

So the gravitation on that planet is twise that on earth.
