Four tiny charged particles (two having a charge +Q and two having a charge -Q)are distributed on the x- and y-axes as shown in the figure. Each charge is equidistant from the origin. In which direction is the net electric field at the point P on the y-axis?
A)directly up (in the +y direction)
B)directly left (-x direction)
C)upwards and towards the left
D)upwards and towards the right
E)The net field is zero, so there is no direction.
