If charges are distributed in the ring which is placed in a x,y plane whose centre is lying on the origin of coordinate as figures. The charge density of the ring is λ=λ0 sinθ where ' θ ' is measured anticlockwise from the positive x-axis, then the net charge on ring is:
a) 2πRσ0
​b) 2πRσ2
c) zero
d) none of these
