Question

11. Ramu is trying to move a heavy stone across the ground. His father gave him cylindrical
rods to help him move it. Give reason

Answer briefly​

Answer 1

Answer:

This is because the rods will cut off the contact between the stone and the ground and will help reduce friction. So it will be easier to move the stone. Hope this helps!!!

Answer 2

Answer:

When Ramu is trying to move the heavy stone the static friction between the heavy stone and the ground is reducing the smoothness which will help Ramu to move the heavy stone quickly. So his father uses the rolling friction with the help of cylinder rods through which the friction can be reduced and it will be smoother for ramu to take the heavy stone wherever he needs.
