Question
An object moves with an acceleration of 3 m s−2 when a force of 30 N is applied. The mass of the body is:
Answer: Option D
:
D
Given, force, F=30 N and acceleration, a=3 m s−2.
Let m be the mass of the body.
We know, F=ma (Newtons's second law of motion)
∴ m=Fa=303=10 kg
Therefore, mass of the body is 10 kg.
