Question

if a man has a mass of 50kg 0n the earth, then what is his weight?

Answer 1

We know that the weight of an object on the surface of the earth is denoted as W.

The expression is given as: mass × acceleration due to the gravity.

⇒m × g

We have to put the values to get:

m × g = 50 × 9.8

= 490 N

The weight of the 50 kg person at the surface of earth is 490 N.

Answer 2

Given :

• Mass of man = 50 kg

To Find :

• Then find the weight of the man on earth

Answer :

• 490 N

Using Formula :

• Weight = Mass × Gravitational acceleration

Solution :

• Weight = Mass × g

• weight = 50 × 9.8

• $\sf \underline{\fbox{Weight = 490 \: \: N}}$
