A block of mass m is at rest relative to the stationary wedge of mass M. The coefficient of friction between block and wedge is mu . The wedge is now pulled horizontally with acceleration a as shown in figure. Then the minimum magnitude of a for the friction between block and wedge to be zero is:

A block of mass m is placed on the top of a 6kg cart such that the time period of the system is 0.75 s assuming there is no slipping. If the cart is displaced by 50 mm from its equilibrium position and released, then the coefficient of static friction mu_(s) between block and cart is just sufficient to prevent the block from sliding. The value of m and mu_(s) respectively are (Take g = 9.8 m//s^(2))
