Force required to move a mass of 1 kg at...

Force required to move a mass of 1 kg at rest on a horizontal rough plane `(μ = 0.1` and `g = 9 .8 m//s^(2))` is

A

`gt0.98N`

B

`lt0.49N`

C

`=0.49N`

D

`lt0.98N`

Text Solution

Verified by Experts

The correct Answer is:
A

`f_(r) = μN =μ`mg`= 0.1 xx 1 xx 9.8 = 0.98` N
(Assuming that the value ofμ= 0.1 is the coefficient of static friction.), so F > 0.98 N.
