An iron block of mass 5 kg is kept on a trolley. If the trolley is being pushed with an acceleration of 5 m/`s^(2)`, What will be the force of friction between the block and the trolley surface (Take the coefficient of static friction between the block and the surface to be 0.8)

A

Zero

B

5 N

C

4 N

D

25 N

Text Solution

Verified by Experts

The correct Answer is:
D
f = `mu mg = 0.8 xx 5 xx 10 = 40` N
Applied force (F) = `5 xx 5 = 25` N
`f_(s) gt F : f = 25 N`
