Question

Two blocks of masses m1 and m2 are placed on a table in contact with each other as shown in the figure below. The coefficient of kinetic friction between the block of mass m1 and the table is μ1, and that between the block of mass m2 and the table is μ2. A horizontal force of magnitude F is applied to the block of mass m1. We wish to find P, the magnitude of the contact force between the blocks.

Answer 1

This should be in the Physics section.

Answer 2

assuming after the force, they move with same accn, we have
F - U1m1 g - P = m1 a
and
P - U2 m2 g = m2 a

eliminate a and solve for P

Answer 3

Adsa, put the question in the Physics section, that way you will get many more answers.
