Question

When a pencil cell is released from a certain point on an inclined wooden board, it travels a distance of 35 cm on floor A before it comes to rest. When the same pencil cell is released from the same point on the same inclined board, it travels a distance of 20 cm on floor B before coming to rest. Wch floor, A or B, offers greater friction? Give reason for your answer.

Answer 1

Answer:

Floor B offers greater friction because it stops the moving pencil cell stop at a lesser distance of 20 cm. more the friction more the surface is rough

Answer 2

Answer:

Floor B offers greater friction because it stops the moving pencil cell stop at a lesser distance of 20 cm on the floor. More the friction, more the surface is rough.
