Two particles `A` and `B` of equal mass `m` are attached by a string of length `2l` and initially placed over a smooth horizontal table in the positoin shown in fig. particle `B` is projected across the table with speed `u` perpendicular to `AB` as shown in the figure. find the velocities of each particle after the string becomes taut and the magnitude of the impulse tension.

Two charged particles having charge 5 uC each are joined by an insulating string of length 1 m and the system is placed on a smooth horizontal table. Find the tension in the string.

A particle of mass m is tied to a string of length L and whirled into a horizontal plan. If tension in the string is T then the speed of the particle will be :

Two particles, each of mass m, are connected by a light inextensible string of lenthe 2l . Initially they lie on a smooth horizontal table at points A and B distant l apart. The particle at A is projected across the table with velocity u. Find the speed with which the second particle begins to move if the direction of u is :- (i) along BA. (ii) at an angle of 120^(@) with AB (iii) perpendicular to AB. In each case calculate (in teerms of m and u) the impulsive tension in the string.

Two particles of mass m and 2m are connected by a string of length L and placed at rest over a smooth horizontal surface. The particles are then given velocities as indicated in the figure shown. The tension developed in the string will be
