Question

The weight of the man on earth is 150 N and on certain planet is 25 N.
Take g=10m/s2 on earth
a.Find the mass of the man on earth and planet
b. Find the acceleration due to gravity on the planet​

Answer 1

Answer:

[ weight is also considered as force ]

w = mg. [ f = mg ]

a. mass on earth = weight/gravity

= 150/10

= 15 kg

mass on certain planet = 25/10

= 2.5kg

b. acceleration due to gravity = weight * mass

= 25N * 2.5kg

= 62.5

hope May it be helpful

Answer 2

We know that,

W = mg [ here w is weight , m is Mass and g is the acceleration due to gravity.]

The weight of the man on earth is 150 N

So,

150 = m × 10

or, m = 150/10 or 15 kg

We know the mass remains the same in all places.

So the mass of the man is 15 kg on earth and on certain planet.

Again,

W=mg

g= W/ m

or, g =25/15 or 1.67 m/s^2

The acceleration due to gravity is 1.67 m/s^2
