28. Two pith balls each with mass m are
32. Three identical point
q, hang from three st
q in terms of m, L, an
suspended from insulating threads. When
the pith balls are given equal positive
charge Q, they hang in equilibrium as
shown. We now increase the charge on
the left pith ball from Q to 2Q while
leaving its mass essentially unchanged. 0
