There are 3 boxes A, B & C of equal masses, same material and similar surface condition, but of different shapes, kept on a rough floor. The surface area of box in contact with the floor varies as C>B>A i.e. box C has the maximum surface area in contact with the floor followed by B and A respectively. Then choose the correct statement

Solution

The correct option is C Force of friction would be same on all the three boxes
Force of friction does not depend upon the extent of surface area in contact with the surface. It solely depends upon the weight of the object and the nature of the surface.
