Question

Fill in the Blank : Two small balls having equal positive charges Q (coulomb) on each are suspended by two insulating strings of equal length L (metre) from a hook fixed to a stand. The whole set-up is taken in a satellite into space where there is no gravity (state of weightlessness). The angle between the strings is . . . . . . and the tension in each string is . . . . . . newton.

Answer 1

the angle between them will be 180 degrees.

and the tension will be (KQ^2)/L^2
