The electric potential at a point (x,y) ...

The electric potential at a point `(x,y)` in the x-y plane is given by `V=-kxy`. The field intentisy at a distance r in this plane, from the origin is proportional to

A

`r^(2)`

B

`r`

C

`1/r`

D

`1/(r^(2))`

Text Solution

Verified by Experts

The correct Answer is:
B
`vecE=(delv)/(delx)hati+(delv)/(dely)hatj" ":.|vecE|=k(sqrt(x^(2)+y^(2)))=kr`
Given ` =-kxy" "Epropr" ":.vecE=kyhati+kxhatj`
