Two masses 1.65 kg and 3.30 kg are joined together by a massles rod parallel to an incline to `30^(@)`, over which both slide down, with the 1.65-kg mass trailing behind the 3.30-kg mass. The coefficient of friction between the first mass and the plane is 0.226 and that between the second mass and the plane is 0.113 Find (a) the tension in the rod, (b) the common acceleration of the two masses
[Hint : Make free-body diagram of the two bodies and consider their motion along and perpendicular to the plane]
