Question
A 10.0-kg box is dragged on a horizontal frictionless surface by a hori- zontal force of 10.0 N. If the applied force is doubled, the normal force on the box will (a) increase; (b) remain the same; (c) decrease.

If the applied force is doubled, the normal force on the box will (a) increase; (b) remain the same; (c) decrease.Explanation / Answer
opition B is correct
since the force on the box along horizontal direction the box is moving only in horizontal direction not in vertical direction so normal force on the box remains same.
