Answer 1

ANSWER:

3rd option

STEP-BY-STEP EXPLANATION:

First, let us consider block A:

By Newton's 2nd law of motion, force horizontal acting on the block A is given by F = m*a

As the block A and B, both are moving with constant velocity, the acceleration is zer .

Therefore:

F = m*a = 0

Then

uF = 0

There will be no horizontal force acting on block A

Now, considering block B:

STEP-BY-STEP EXPLANATION:

First, let us consider block A:

Making the same analogy as in block A in block B, we have the following (F = uF):

Therefore, the correct option is the diagram of the 3rd option
