Responses
A The effort force is greater than the force of gravity on the block.The effort force is greater than the force of gravity on the block.
B The effort force is less than the force of gravity on the block.The effort force is less than the force of gravity on the block.
C The effort force is equal to the force of gravity on the block.The effort force is equal to the force of gravity on the block.
D There is no gravity on the block if it rests on the table.

C The effort force is equal to the force of gravity on the block.
