A wedge of mass $\displaystyle \mathrm{M}=4 \mathrm{~m}$ lies on a frictionless plane. A particle of mass m approaches the wedge with speed $\displaystyle v$. There is no friction between the particle and the plane or between the particle and the wedge. The maximum height climbed by the particle on the wedge is given by :
