What will be the mass of the girl weighing 450 N?

Solution (By Examveda Team)

Weight is the gravitational force acting on an object and is related to mass by the formula:

Weight (W) = Mass (m) × Acceleration due to gravity (g)

Where:

W = 450 N (Weight of the girl)

g = 9.8 m/s² (Standard acceleration due to gravity)

m = ? (Mass of the girl)

Rearranging the formula:

Mass (m) = Weight (W) ÷ g

Substituting the given values:

m = 450 ÷ 9.8 ≈ 45.9 kg

Therefore, the mass of the girl is approximately 45.9 kg.

Remember: Mass is measured in kilograms (kg) and remains the same everywhere, whereas weight is measured in newtons (N) and depends on the value of gravitational acceleration. Therefore, a person can have the same mass but different weights on different planets.
