Two planes which are doubly inclined at angles ∠????to the horizontal meet in a ridge.
Particles of masses 4?? ??? 3?? rest one on each plane respectivelyand are connected
by a light inextensible string which passes over q smooth pulley onthe ridge. Find the
tension and acceleration of the system if; (a.) both planes aresmooth (b.) the coefficient of
friction at each contact is 1 /√3
