Question

find the gravitational potential energy of the books. If the weight of each book is 10N. Book A=3m,book B=4m, book=2m
Pls help

Answer 1

Answer:

Sir Newton's third law of motion states that for an action there is always an equal and opposite reaction . These two forces always act on different objects . When a book is kept on a table , weight (gravitational force) of book acts on table  vertically downwards and as a reaction of weight , table also exerts an equal and opposite ( upward) force on book
