Question

What are the magnitude and direction of the electric field at the center of the square in the figure, if q = 1.0 x 10-8 C and a = 5.0 cm?​

Answer 1

Answer:

ans will be 0

note-

if the polygon is regular and the charges are same

then the net electric field at the centre will be 0

here the polygon is square and it is regular and also the charges are same. Therefore the net electricfield at centre will be 0

hope it helps ☺
