Two equally charged pith balls of equal mass are separated by a distance
r
, due to their mutual electrostatic repulsion. Each ball hangs on a string of length
l
from a common point, making an angle
θ
with the horizontal. The value of the angle
θ
, the charge
q
, and the tension
T
of the string are calculated.
