2 cards from this section. Quick, good the night before a test.
Define an electric dipole.
Think about how charges are arranged.
What is a dipole moment?
It has both direction and magnitude.
What is a dipole moment?
Remember how it is defined.
True or False: Electric dipoles have a net charge.
Think about charge distribution.
A dipole of charge ±2 × 10^-6 C is oriented at 45 degrees to an electric field of 1000 N/C. Calculate the torque acting on it.
Use the formula involving torque and remember to convert angles to radians if necessary.
Explain how dipole forces lead to polarization in materials used in capacitors.
Consider how charge distribution changes under electric fields.
