A block of mass 1 kg is placed on a truck which accelerates with acceleration 5m/s². The coefficient of static friction between the block and truck is 0.6. The frictional force acting on the block is
-
- 5 N
- 6 N
- 5.88 N
- 4.6 N
Correct Option: A
Maximum friction force = µmg
= .6 × 1 × 9.8 = 5.88 N
But here required friction force
= ma = 1 × 5 = 5 N
