Two blocks of masses m and M are connected by an inextensible light string as shown in the figure. When a constant horizontal force F acts on the block of the mass M , then tension in the string is : (Assume that constact between the ground and the two blocks are frictionless) and blocks will not topple. (Given: m = 1 kg, M = 4 kg, F = 10 N, theta = 60^(@) )

A block of mass m is kept over another block of mass M and the system rests on a horizontal surface. A constant horizontal force F acting on the lower block produces an acceleration (F)/(2(m+M)) in the sytem. The two blocks always move together. Consider displacement d of the system. a.
