At a point on the right bisector of a magnetic dipole the magnetic potential

Options

A. potential varies as `(1)/(r^(2))`
B. Potential is zero at all points on the right bisector
C. field varies as `r^(2)`
D. Field is perpendicular to the axis of dipole

Answer

A

Explanation

`V=(mu_(0))/(4pi)(MaStheta)/(r^(2))`
At right side of bisector,`theta=0`
`therefore V oo(1)/(r^(2))`
