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 sin θ 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
