Question

a body of mass 10 gram is moving with a constant velocity of 4 cm per second on a frictionless table calculate the force on the table

Answer 1

I think that the answer to this question will be 0. I will show you how.

F=ma

m=10gms or 0.01kg

a= 0 m/s^2 (constant velocity means 0 acceleration)

F=(0.01 kg)(0 m/s^2)

F= 0N

Answer 2

Answer:

F = 0 N

Explanation:

Given that,

Mass of the body, m = 10 gm = 0.01 kg

Constant velocity, v = 4 cm/s

As the body is moving with constant velocity. So, the change in velocity of the body is equal to 0. As a result its acceleration is 0 because it is given by :

a = change in velocity/charge in time = 0

So, $F=m\times a=0$

So, the force on the table is 0 newtons. Hence, this is the required solution.
