A stone with a mass of 10 kg sits on the ground. The normal force acting on the stone, keeping it at rest, is 98 N. The correct option is D.
What is force?
A force is a power that changes the position of an object. This results in the action or movement of any object. Force is calculated in Newton. The force can be calculated by multiplying the mass by acceleration.
Given, the mass of the stone is 10 kg
The gravitational force act at the rate of 9.8 m/s²
The formula is
Force = mass x gravitational rate
Fn = normal force
m = mass of the stone
g = gravitational force acting on the stone
So, fn = m x g
10kg x 9.8 m/s²
98 kg m/s²or 98 N
Therefore, the normal force acting on the stone, keeping it at rest, is 98 N. The correct option is D.
