Question
The radius of Earth is about 6400 km and that of mars is 3200 km. The mass of the Earth is 10 times the mass of mars. An object weight 200 N on the surface of Earth. Its weight on the surface of mars will be : -
Options
A.80 N
B.40 N
C.20 N
D.8 N
Solution
g = 
⇒
R is reduced to R/2 and the mass of the mars becomes 10 times
gmars =
gearth and Wmars = 
Wearth = 80N.
⇒ R is reduced to R/2 and the mass of the mars becomes 10 times
gmars =
gearth and Wmars = Wearth = 80N.Create a free account to view solution
