Answer 2

Given: Rahul pushes a book of mass 2 kg on the table from point A to point B, which are 1 m away from each other.

To find: We have to find out the force.

Solution:

We know that according to Newton's second law-

F=mga

Where F is the force need to push a object and has unit Newton.

m is the mass of the object.

g is the gravitational force having value $10m/s^2$.

h is the height of the object.

Now work done can be given as-

W=F×d

Where d is the displacement.

W=2×10×1

W=20

The work done by the gravitational force on the book is 20N.
