A block of mass `10kg` is placed on a rough horizontal surface having coefficient of friction `mu=0.5` . If a horizontal force of `100N` is acting on it, then acceleration of the will be.

A

10 `m//s^2`

B

5 `m//s^2`

C

15 `m//s^2`

D

0.5 `m//s^2`

Text Solution

Verified by Experts

The correct Answer is:
B
`f_"max"=muN=muMg=(0.5)(10)(10)=50 N`

`rArr` a=`"net force"/"mass"`
`=(100-50)/10`
`=5m//sec^2`
