On the horizontal surface of a truck (µ=0.6),a block of mass 1 kg is placed. If the truck is accelerating at the rate of 5m/sec² then frictional force on the block will be

Open in App

Solution

The maximum frictional force acting will be μmg=6x1x10=6N
But pseudo force acting on the body is ma=1×5=5N
Since pseudo force < frictional force
the frictional force acting is only 5N
