An electric dipole is formed by `+ 4 mu C ` and `- 4 mu C`charges at 5 m m distance. Calculate the dipole moment and give its direction.

Text Solution

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.
