Question

A book whose mass is 2 kg rests on a table. Find the magnitude of force exerted by the table on the book solution

Answer 1

F=mg

taking g=10m/sec^2

m=2kg

therefore:

F=2×10

F=20N

according to newton's third law of motion every action has an equal and opposite reaction.

So,the table exerts a force of 20N on the book.
