A charge Q is divided into two parts q_(1)andq_(2) such that they experience maximmum force of repulsion when separated by cetain distance .The ratio of Q q_(1)andq_(2) is

`1:1:2`

`1:2:2`

`2:2:1`

potential is zero at a point on the axis which is ` x//3` on the right side of the cahrge `-q//4`

potential is zero at a point on the axis which is `x//5` on the left side fo the charge `- Q//4`

electric field is zero at a point on the axis which is at a distance `x` on the right side fo the charge `- Q//4`

there exist two points on the axis where electric field is zero.

Force is equal in magnitude for both but opposite in direction

Force is dependent on the medium in which charges are placed

Force is maximum irrespective of medium in which charges are placed

None of the above
