Question 2.
Define dipole moment.
Show hintHide hint
Consider how dipole strength relates to both charge and distance.
3Question 3.
What is the formula for electric potential due to an electric dipole?
- V = (1/4πε₀)(p·r̂/r)
- V = (1/4πε₀)(p·r̂/r²)
- V = (1/4πε₀)(q/r²)
Show hintHide hint
Recall the components of dipole potential.
4Question 4.

- True
- False
Show hintHide hint
Consider the effect of charges and distance.
Question 5.
Given a dipole with p = 3 × 10^-29 C m and located at a distance of 0.1m from a point in space, calculate the potential at that point.
