1.	A block of mass m is placed on the top of another block of mass M as shown in the figure. The coefficient of friction between them is mu. The maximum acceleration with which the block M may move so that m also moves along with it is
Answer» `MU g` `mu(M)/(m) g` `mu(m)/(M) g` `(g)/(mu)` SOLUTION :(a) m will move by FRICTION, `f_("max")=mu mg implies(a_(m))_("max")=(mu mg)/(m)=mu g`
