A 90 kg body is taken to a planet where the acceleration due to gravity is 2.5 times that of the earth. What is the weight of this body
on the surface of this planet? Take g = 10 m/s?.

225 kg.

Explanation:

Since the gravity is 2.5 times than that of the Earth, g on that planet = (10 * 2.5) m/s = 25 m/s.

Hence, the weight of the body would be (90 * 2.5) kg, aka 225 kg.

Hope this helped!

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
