Figure shows two large cylindrical shells having uniform linera charge densities `+ lambda` and `- lambda`. Radius of inner cylinder is 'a' and that of outer cylinder is 'b'. A charged particle of mass m, charge q revolves in a circle of radius r. Then, its speed 'v' is : (Neglect gravity and assume the radii of both the cylinders to be very small in comparison to their length.)

A

`sqrt((lambda q)/(2pi in_(0) m))`

B

`sqrt((2 lambda q)/(pi in_(0) m))`

C

`sqrt((lambda q)/(pi in_(0) m))`

D
