Question

The weight of the man on the earth is 150N and on certain planet is 50N.

What is its mass on the earth? What is the acceleration due to gravity on

the planet?​

Answer 1

Answer:

weight of man in earth - 150N

weight of man in planet X - 50N

as we know , W = mg

We = mg ------> weight on earth

150 = m × 9.8

m = 150/9.8

m = 15.3 kg -----> mass of man in earth .

As we know that mass is constant in the universe ,whereas the weight will change .

so, Wx = mg

50 = (15.3)g

gx = 50/15.3

gx = 3.26m/s² -----> gravity in other planet ..
