Figure shows a non-conducting semi-circular rod in x-y plane. Top half (quarter circle) has uniform linear charge density -\\lambda whereas remaining half has uniform linear charge density +\\lambda. What is the direction of the net electric field at point P ?

Correct Answer is : Along +y axis

Electric field is zero at point P, so direction cannot be determined

Along the bisector of x -axis and y -axis
