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

`(mv^2)/(2L)`

`(3mv^2)/(4L)`

`(4mv^2)/(3L)`

`(8mv^2)/(3L)`
