Two boys A and B find the jumble of n ropes lying on the floor. Each takes hold of one loose end randomly. If the probability that they are both holding the same rope is `1/101`, then the number of ropes is equal to

6 boys and 6 girls are randomly divided into two equal groups. Find the probability that each group contains same number of boys and girls.

A rope of length L and mass M is being pulled on a rough horizontal floor by a contact horizontal force F = m g . The force is acting at one end of the rope in the same direction as the length of the rope. The coefficient of kinetic friction between rope and floor is 1//2 . Then the tension at the midpoint of the rope is

A rope of length of 2m is tied between two ends . If the speed of transverse waves propagating in the rope is 4 m s^(-1) and the tension in the rope is 2 N , find the mass of the rope is C.G.S units .

A rope of length L and mass M is being pulled on a rought horizontal floor by a contact horizontal force F = m g . The force is acting at one end of the rope in the same direction as the length of the rop. The coefficient of kinetic friction between rope and floor is 1//2 . Then the tension at the midpoint of the rop is

A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m as shown in A horizontal force F is applied to one end of the rope. Find (a) the acceleration of the rope and block (b) the force that the rope exerts on the block (c) the tension in the rope at its mid point
