A single horizontal force F is applied to a block of mass M1 which is in contact with another block of mass M2 if the surfaces are fictionless find the force between the blocks
Answers
A single horizontal force F is applied to a block of mass M1 which is in contact with another block of mass M2 .
we know, if two objects is placed in contact with each other then, normal reaction force acts between them.
so, Let N is normal reaction acts between them.
now, for 1st block,
F - N = M1a , .......(1)
where a is acceleration of block.
for 2nd block,
N = M2a .......(2)
from equations (1) and (2),
F = (M1 + M2)a
a = F/(M1 + M2)
and N = M2a = M2 × F/(M1 + M2)
= M2F/(M1 + M2)
hence, the force between the blocks is M2F/(M1 + M2)
