On the horizontal surface of a truck `(mu=0.6)` a block of mass 1 kg is placed. If the truck is accelerating at the rate of `5m//sec^(2)` then friction force on the block will be

A

5 N

B

6 N

C

5.88 N

D

8 N

Text Solution

Verified by Experts

The correct Answer is:
A
`f_(s) = mu mg = 0.6 xx 1 xx 10 = 6 N`
`F = ma = 5N`
Since , `f_(S) gt F`
`therefore` Friction force (f) = 5 N
