Four equal charges, q=8.61C, of mass m 8.61kg are at the corner of a square of side L=0.0265m.
(a) If an equivalent charge of the same mass is placed at the origin, what is its speed at any time after it is released?
(b) If a charge of equal mass but opposite charge is placed at the origin, what is its speed at any time after it is released?
(c) If a charge of equal mass but opposite charge is placed at the midpoint of one of the side of the square, what is its its potential energy at that point? Express your result with at least 4 significant figures.
(d) If the charge in part (c)
