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

`0.5 m//s^(2)`

B

`5 m//s^(2)`

C

`10 m//s^(2)`

D

`15 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`f = mu mg = 0.5 xx 10 xx 10 = 50 N`
`a = (F - f)/(m) = (100 - 50)/(10) = 5 m//s^(2)`
