A mass M is suspended by a rope from a rigid support at A as shown in figure. Another rope is tied at the end B ,
and it is pulled horizontally with a force. If the rope AB makes an angle θ with the vertical in equilibrium then the tension in the string AB is ,
Two blocks m1 = 4kg and m2 = 2kg ,
A uniform of rope length L and mass M is placed on a smooth fixed wedge as shown. Both ends of rope are at same horizontal level. The rope is initially released from rest, then the magnitude of initial acceleration of rope is.
