The dipole moment of a dipole is 4 xx 10^(-9) Cm. The po1ential of a point away from 0.2 rn, the direction maJting an angle 60^(@) with axis of dipole is .........

Answer»

`4.5 `V
45 V
450 V
4500 V

Solution :`V = (kq COS theta)/(r^(2))=(9XX10^(9)xx4xx10^(-9)xxcos 60^(@))/((0.2)^(2))`
`= (3.6xx1)/(0.04xx2) = 450 V`
