Question

raj and Geeta have a metal cuboid Box with them Raj said that the different surface of the box have different frictional force Geeta said that the frictional force is independent of area of contact and so the frictional force is same for any surface of the box whose answer do you support explain​

Answer 1

Answer:

Geeta's answer is correct.

When the small side is in contact, there are fewer 'hills' but the area of each one is larger due to the higher pressure (same force, smaller area), so there will be no difference in the amount of friction.
