Question

A block is at rest on a table. A girl applies a force towards the right. The applied force is
equal to the frictional force between block and the surface. What will happen to the block?
(a)it starts rotating
(b)it does not move
(c)it will start sliding towards left
(d)it will start sliding towards right

​

Answer 1

Answer:

it does not move

Explanation:

Because the net force is zero

Answer 2

When the girl applies a force towards the right, the block does not move.

• Frictional force is the force that exists between the block and the table.
• It resists the motion of the block.
• If the force applied by the girl is the same as the frictional force acting between the block and the table, then the net force on the block becomes zero.
• This means that two equal opposite forces are acting on the block.
