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:

`(hC)/(Ve)`

`(Ve)/(h)`

`(V)/(hC)`
