Acceleration due to gravity of earth, g= 9.8 m/s2
Therefore,
weight of the body with mass 25 kg on earth will be = m*g = 25* 9.8m/s2 = 245 N
On planet whose mass is twice as Earth and radius is half of earth,
Weight of planet =2me
radius of planet =re/2
so ,
weight of the body on planet =250×2=500N
and mass will be 25×2 =50kg
Therefore,
weight of the body with mass 25 kg on earth will be = m*g = 25* 9.8m/s2 = 245 N
On planet whose mass is twice as Earth and radius is half of earth,
Weight of planet =2me
radius of planet =re/2
so ,
weight of the body on planet =250×2=500N
and mass will be 25×2 =50kg
