Question

2m
m
Two blocks are in contact on a frictionless table. A
force Fis applied on 2m as shown in the figure. The
force of contact between the two blocks is
(1) F/3
(2) F/2
(3) F
(4) 2F/3​

Answer 1

Answer:

If F is the applied force then acceleration of the system is F2m+m=F3m.

Now when we are applying the force from the left, the force applied on the block m is F3mm=F3. This will be the force in the contact.

When we apply the force from the right from on the block will be F3m2m=2F3, this will be the force on the contact then.

So the ratio is F3:2F3=1:2

 

Hope this information will clear your doubts about force.
