Charges `pm20` nC are separated by 5 mm. Calcuate the magnitude and direction of dipole moment.

Text Solution

Verified by Experts

Given, `q_(1)=q_(2)=pm20nC`
`=pm20xx10^(-9)C`
Distance `=2l=5mm`
`=5xx10^(-3)m`
`:.` dipole moment, `p=q(2l)=20xx10^(-9)xx5xx10^(-3)`
`=10^(-10)"C-m"`
The direction of p is from negative charge to positive charge.
