Four point +ve charges of same magnitude (Q) are placed at four corners of a rigid square frame as shown in figure. The plane of the frame is perpendicular to z -axis. If a -ve point charge is placed at a distance z away from the above frame (z lt lt L) then negative 1). charge oscillates along the Z-axis 2).it moves away from the frame 3).it moves slowly towards the frame and stays in the plane of the frame 4).it passes through the frame only once
