Question

A force of 20 N acts upon acts a body whose weight is 9.8N.what is the mass of the body and how much is it's acceleration?

Answer 1

Answer:

Mass of body = 1 kg

Acceleration due to gravity = 9.8 m/s²

Step-by-step explanation:

Given - External force = F = 20 N

Body weight W = 9.8 N

Weight = Mass × Acceleration of gravity

∴ 9.8 N = M kg x 9.8 m/s²

∴ M = 9.8 ÷ 9.8

∴ M = 1 kg

Mass of the body = 1 kg.

As the force acting on the body is constant an not changing, there will be no change in its acceleration.

Thus, accelaration acting on the body = Accelaration due to gravity = 9.8 m/s²
