Question

Two small balls having equal positive charge q coulomb are
suspended by two insulating strings of equal length ' l ' meter
from hook fixed to stand The whole setup is taken in a satellite
into sapce where there is no gravity What is the angle between the
two strings and the tension in each string?

Kranav Sharma · Accepted Answer

Here, the angle between the two strings will be 180 degrees,
while, the tension will be equal to the coulomb force of repulsion
between the two positive charges it will be
F = T = kq2 / r2 = kq2 /
(2l)2
here r = 2l, the distance between the two charges
