Question

A stone resting on the ground has a gravitational force of 20 N acting on it. What is the weight of the stone? What is its mass? (g = 10 m/s²).

Answer 1

Given Data:

• Gravitational force acting on the stone (F_g​) = 20 N
• Acceleration due to gravity (g) = 10 m/s²

1. Weight of the stone:

The weight of an object is the gravitational force acting on it.
So, the weight of the stone = 20 N

2. Mass of the stone:

We know the relationship between weight and mass:

F_g​ = m × g

Rearranging to find mass (m):

`m = F_g/g`

Substitute the values: `m = 20/10 = 2  kg`

Final Answers:

• Weight of the stone = 20 N
• Mass of the stone = 2 kg
