two blocks of masses m1 and m2are placed in contact with each other on a horizontal platform . the coefficent of friction between m1 and the platform is 2µ and between block m2 and platform is µ . the platform moves with an acceleration a . the normal reaction between the blocks is:
a. zero in all case
b. zero only if m1 = m2
c. non zero only if a > 2µg
d. non zero if a > µg
dear rohan bhatia
in this question relative position of blocks and direction of acceleration of plateform is not given
so i will take a perti cular case
in the diagram normar reaction between block is taken zero
and shown frictional force is maximum
max acc for block m1=2µg
max acc for block m2=µg
clearly when a>µg slipping occure and there must have normal reaction betwwen blocks
so option c and d is correct
normal reaction is zero for a<ug
