Read the given passage and answer the questions
46 and 47.
The force of friction not only tends to stop a moving object, it also tends to stop a stationary object from moving. That is why it is difficult to push a stone to get it to move on a rough surface.
Friction is almost independent of.
(i) velocity of moving body
(ii) Weight of moving body
(iii) Nature of contact surface of moving body
(iv) Shape of moving body
A(i) and (iv)
B(ii) and (iii)
DNone of these
when velocity is 0 static friction comes into play and when the velocity increases kinetic fraction comes into action and thus the friction decreases
