Question

When you and your friend push a table in opposite directions, it becomes difficult to move. This is because:

• A. the net force becomes the sum of the two forces.
• B. the net force becomes the difference of the two forces.
• C. the table becomes heavier.
• D. the table becomes lighter.

Answer 1

The correct option is B the net force becomes the difference of the two forces.

When two forces are applied in opposite directions, the net force becomes the difference of the two. So, the net force becomes small and the table becomes difficult to move.
