Solve the following question:
Question: Four blocks EACH of mass m = 10 kg are arranged as shown in the picture, on top of a frictionless table. A hand touching block 1 applies a force of Fh1 = 90 N to the right. The coefficient of friction between the blocks is sufficient to keep the blocks from moving with respect to each other.
Part A: What is the total force exerted by block 2 on block 3?
I know the correct answer for above querstion but explain how to get this answer! Thanks.
