An object of mass 5 kg is sliding on a smooth frictionless horizontal surface with a constant velocity of 10 m/s. the force required to keep the object moving with the same velocity is

A

250 N

B

500 N

C

0 N

D

50 N

Text Solution

Verified by Experts

The correct Answer is:
D
Given that,
`m=5kg,v=10m//s,t=1s`
We know that, `F=ma=((mv)/(t))`
`=(5xx10)/(1)=50N`
