Answer

The force on the left across the lab table.

Step-by-step explanation

The Newton's third law of motion states that; action and reaction are equal but a ct in opposite direction.

When the block of is pulled on the right with a force of X Newtons then there is a force -X Newtons applying and equal force on the left. For every action there must be a reaction with is equal and applying in the opposite direction.

So, if the block is pulled on the right by a force of 8 N there is another equal force applying on the left.
