Challenge Problems
Push your limits with challenges.
Question 1
A dipole consisting of charges 2 µC and -2 µC is separated by a distance of 0.02 m. Calculate the dipole moment. Then find the electric field strength at a point 0.5 m away on the axial line.
💡 Hint: Break it down into two parts: find the dipole moment first, then apply the axial electric field formula.
Question 2
If a dipole separated by a distance of 0.1 m has an electric field of 3 × 10⁶ N/C at a point on its axial line, what is the dipole moment?
💡 Hint: Remember to rearrange the formula for dipole moment after substituting known values.
