Answer 2

Given weight of the body , w  = 45 kg

We need to find the mass of the body.

Generally many people think that mass and weight are same. But in reality they are not same.

There is a relation between mass and weight of the body.

i.e., $\bold{\bf{\blue{Weight=Mass*Gravity}}}$

⇒ w = m g

We know that gravity of the earth is 9.8 m/s.

⇒ 45 = m (9.8)

⇒ m = 4.58 kg

So the mass of the body is 4.58 kg
