0Two blocks of masses \( m_{1} \) and \( m_{2} \) are placed in contact with each other on a horizontal platform. The coefficient of friction between the platform and the two blocks is the same.
The platform moves with an acceleration. The force of interaction between the blocks is :
(A) Zero in all cases
(B) Zero only if \( m_{1}=m_{2} \)
(C) Non zero only if \( m_{1}>m_{2} \)
(D) Non zero only if \( m_{1}<m_{2} \)
