Question

A force F is applied to block A , which is placed on top of block B, causing it to slide over block B. There is friction between block A and block B, but not between block B and the floor how will you compare the magnitude of the friction forces acting on block A and block B?

a: fa>fb

b: fa<fb

c: fa=fb

d: depends on the direction of force F

e: depends on magnitude of force F

Part B

The direction of fa and fb are ( force F is being applied to the left on block a )

A: a towards right and b towards left

B: a towards left and b towards right

C: a towards left and b towards left

D: a towards right and b towards right

E: depends on which mass is larger.

Explanation / Answer

Part A

e : frictional force depend upon the magnitude of force F applied on block A

Part B:

A : a towards right and b towards left
