1.

Two point charges +q_(1) and -q_(2) are placed at A and B respectvely. An electric line of force emerges from q_(1) making an angle alpha=60^(@) with line AB and terminates as -q_(2) making an angle of 90^(@) with line AB. (a). Find |(q_(1))/(q_(2))| ltbr. (b). Find the maximum value of angle alpha at which a line emitted from q_(1) terminates on charge q_(2).

Answer»


ANSWER :(a). `|(q_(1))/(q_(2))|=(2)/(1)`
