Question

A 5 kg book rests on a table. How much force is it exerting on the table?

Answer 1

Answer:

WE know that

F = MA

here

M = 5kg

A = 9.8m/s-1 or 10

hence F

= 5 ×9.8

48 NEWTON force

Answer 2

The force exerting on the table because of book = 49 N

• Given that weight / mass of the book is 5 kg and its rest on the table
• As we know the force acting on a object due to the gravitational force  F = mg where m is mass of object and g the acceleration due to gravity  

• We know that the value of g =  9.8 m/s⁻¹

Therefore,

The force acting on the table = mass of book × g

                                              F = 5 kg × 9.8 m/s⁻¹  = 49 N

The force exerting on the table because of book = 49 N
