Joe pushes a box with a force of 16 N to the left. Ann pushes the same box from the opposite side with a force of 10 N to the right. What will be the result?

• The box will move up because of a combined force of 26 N.

• The box will not move because 6 N is not enough to move it.

• The box will move to the left because of a net force of 6 N.

• The box will move to the right.
