Questions
The electric potential at a point (x, y) in x-y plane is given by V = - k (xy). The field intensity at a distance r from the origin varies as
detailed solution
Correct option is B
Given that V = -k x yEx=−∂V∂x=kyand Ey=−∂V∂y=kx∴ Er=Ex2+Ey2=k2y2+k2x2=kx2+y2=k⋅rSo, Er∝r.Talk to our academic expert!
