Question

A BOOK PLASED ON A SURFACE OF A TABLE THE BOOK IS PUSHED IN ONE DIRECTION DRAW THE FORCE ACTING ON THE BOOK AND EXPLAIN

Answer 1

suppose a book placed on a table and some force is applied on it then it will move in the direction of the force then, the force which act on it are:- force of friction =which act opposite the applied force. mg=weight due to gravity. R(normal reaction)=which balance the the force mg.

Answer 2

Note:-

f = Frictional Force

V = Applied force

W = Gravitational force

N = Normal force

Forces acting on a book:-

(i) Weight of the book (W) or gravitational force acting vertically down.

(ii) Normal force (N) reaction force applied by the floor vertically up.

As there is no change in motion of the book along the vertical direction, the net force acting on the book in the vertical direction is Zero.

That is, W - N = 0 => W = N

HOPE THIS HELPS...
