Question

Two charges + 15 UC and-15 UC separated by a distance of 1 u m. What is the dipole moment?

Answer 1

Hi,

Here is your answer

Given:

Charge (q1)=15μC= 1.5×10^-5 C

Charge (q2)= -15μC= -1.5×10^-5C

Distance(d)=1mm=10^-3m

To find:

Dipole moment(p)

Solution:

The equation for finding dipole moment is given by

p=q×2d

Substituting the given datas in the equation

We get,

p=1.5×10^-5×2×10^-3

p=3×10^-8C m

Notes:

1. Remember to convert all the given datas to their SI units before calculating.

2. Dipole moment is defined as the product of any one of the charges and separation between them. It is a vector quantity

3. The direction of dipole moment is from negative to positive.

4. The unit of dipole momet is Coulomb metre(C m)

Hope this helps you.
