The plates of a parallel-plate capacitor are given equal positive charges. What will be the potential difference between the plates? What will be the charges on the facing surfaces and on the outer surfaces?

A particle executing simple harmonic motion comes to rest at the extreme positions. Is the resultant force on the particle zero at these positions according to Newton's first law?

Draw three equipotential surfaces corresponding to the field whose magnitude increases uniformly, but remains constant along the z-direction. How are these surfaces different from those that lie along the z- direction of a constant electric field?
