A particle of mass `5kg` is moving on rough fixed inclined plane with constant velocity of `5m//s` as shown in the figure. Find the friction force acting on a body by plane.

A

`25N`

B

`20N`

C

`30N`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`Sol. F_(k)=mu_(k)N=mu_(k) mg cos 30^(@)=mg sin 30^(@)`
`=5(10)((1)/(2))rArrf_(k)=25N`
