A system has two charges `q_(A)=2.5xx10^(-7)C` and `q_(B)=-2.5xx10^(-7)C` located at points `A-=(0,0,-15cm)` and `B=(0,0,+15cm) `respectively. What are the total charge and electric dipole moment of the system?

Text Solution

Verified by Experts

a. Net charge of the system `=q=` zero
b.

The distance between the dipoles `=2(15)=30cm =0.30m`
Dipole moemnt `=2aq`
`=0.30xx2.5xx10^(7)`
`0.75xx10^(-7)cm`
`=7.5xx10^(-8)` cm along the z-axis.
