Underline your best choice on the following situations:Amy holds an orange with a mass of 200 g at rest on the palm of her righthand.1. How much force is acting on the apple?[-1 N][1 N][2 N][-2 N]2. The downward force W exerted on the apple is caused by[Earth][her hand]3. Amy's hand supports the apple with upward force N. We can say that N[equals W][has the same magnitude as W]4. Since the apple is at rest, the net force on the apple is[zero][nonzero]5. Since N have equal value with W, we [can] [cannot] say that N and Wcomprise an action-reaction pair. The reason is because action andreaction always [act on the same object] [act on different objects].
