a charge is placed at teach of the opposite corners of square. A charge q is placed at each of the other two corners. If the net electrical force on Q is zero, then the Q/q equals
Hello candidate,
At each of these four corners off the square four charges are placed with charges Q and q at adjacent corners.
It's Mention that the net electrostatic force on the charge Q is zero, so upon adding all the electrostatic forces in vector addition we get the ratio of Q/q is equal to 2√2, where the formula of electrostatic force is given by kq1×q2/ r^2.
Hope this answer was helpful!!
Good luck.
