Verified by Experts

Dipole moment`p= 2aq` where , total separation `2a = 5 xx 10^(-3) m ` and `q= 4 xx 10^(-6) C`
`:. ` Dipole moment `p = 5 xx 10^(-3) m xx 4 xx 10^(-6) C = 20 xx 10^(-9) Cm`
And its direction is taken from negative to positive charge.

An electric dipole consists of two opposite charges each of magnitude 1 mu C separated by a distance of 2cm. The dipole is placed in an external of 10^(5) N //C . The maximum torque on the dipole is

`2 xx 10^(-4) Nm`

`2 xx 10^(-3) N m`

`4 xx 10^(-3) Nm`

`10^(-3) Nm`

An electric dipole is kept on the axis of a uniformly charged ring at distance d from the centre of the ring. The direction of the dipole moment is along the axis. The dipole moment is p , charge of the ring is Q & radius of the ring is R . The force on the dipole is

`(pQ)/(3piepsilon_(0)sqrt(3)R^(2))`

`(4pQ)/(3piepsilon_(0)sqrt(3)R^(2))`

`(pQ)/(3piepsilon_(0)R^(2))`

zero

An electric dipole has the magnitude of its charge as q and its dipole moment is p. It is placed in a uniform electric field E. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively

2qE and minimum.

qЕ and pE.

zero and minimum.

qE and maximum.
