Transcribed Image Text:(a) 12 electrons (of charge -e) are
equally spaced and fixed around a circle of radius R. Relative to
= 0 at infinity, what are the electric potential and electric field at
the center C of the circle due to these electrons. Draw the figure
this configurasion. (b) If the electrons are moved along the
circle until they are nonuniformly spaced over 120° arc as
shown in the given figure (b), What then is the potential at C?
How does the electric field at C change ( if at all) ? (c) Draw the
equipotential surfaces for a single positive charge. (d) Draw
the equipotential surfaces for two charges, one is positive & the
other is negative point charge separated by a distance d.
