Question

The mass of a body is 20.0 kg. Taking the pull of gravity on mass 1 kg equal to 10 N, express the weight of the body in Newton.​

Answer 1

Mass = 20 kg

Acceleration due to gravity = 10 m/s²

Weight = mg = 20 × 10

= 200 N

Answer 2

Given :

• Mass = 20 kg

• 1 kg = 10 N

To Find :

• We need to express the weight of the body in Newton.

Solution :

• As we know that,

➩ F = ma

• Now, Substituting the given values we get :]

➩ F = 20 × 10

➩ F = 200 Newton

Therefore, weight of the body is 200 Newton.
