An electric dipole of length 10cm having charges `+- 6xx10^(-3) C`, placed at `30^(@)` with respect to a uniform electric field experiences a torque of magnitude `6 sqrt(3) N-m`. Calculate (i) magnitude of electric field (ii) the potential energy of dipole.

Text Solution

Verified by Experts

`tau = ( 2 a Q ) E sin theta`
Given ` 2 a = 10 cm ` and `Q = 6 xx 10^(-3) C`
`:. E = 2 sqrt( 3) xx 10^(4) N //C`
