Question

Three identical point charges ( q = +2.7 uC) are place on the corners of an equilateral triangle whose sides have a length of 35 cm.
What is the magnitude of the electric field at the centre of the triangle?

Answer 1

Answer:

ans will be 0

Note -

if the polygon is regular and the charges at each corner are same then the net electric field at the centre will be 0

here the polygon is equilateral triangle. so it is regular

and the charges at each corner are same. so electric field will be 0

hope it helps ☺
