A block is stationary on an inclined plane If the coefficient of friction between the block and the plane is mu then .

Two identical blocks A and B are placed on a rough inclined plane of inclination 45^(@) . The coefficient of friction between block A and incline is 0.2 and that of between B and incline is 0.3 . The initial separation between the two blocks is sqrt(2)m . The two blocks are released from rest, then find the time (in sec) after which front faces of both blocks come in same line.
