It is an imaginary concept used to represent electrostatic force. The lines arise from positive charge and terminate on negative charge. More the number of electric field more the strength of electrostatic force.

ANSWER

Two small balls, each having a positive charge q coulomb, are suspended by two insulating strings of equal length l meter from a hook fixed to a stand. The whole set up is taken in a statelite into space where there is no gravity. The angle between the two strings and the tenstion in each string will be
