Question

A block of mass 0.1 kg is held against a wall by applying a horizontal force of 5 N on by the block. If the coefficient of friction the between the block and the wall is 0.5, the magnitude of the frictional force acting on the block is a) 2.5 N b) 0.98 N c) 4.9 N d) 0.49 N​

Answer 1

Answer:

c is the answer

Answer 2

Answer:

correct answer is O.98N

Explanation:

The maximum frictional force can be 5\times 0.5=2.5N

But the frictional force is only balancing the weight of the object, so it's value will be 0.98 N.
