In Fig block 1 is placed on top of block `2` .Both of then have a mass of `1 kg` The coefficient of friction between block 1 and 2 are `mu_(s) = 0.75` and `mu_(k) = 0.60` The table is frictionless A force `p//2` is applied on block `1 ` in the left and force `P` on block `2` to the right .Find the minimum value of `p` such that sliding accore between the two blocks
