Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
It is given that,
Side of square,
It is given that, the potential at point c is equal to zero.
So, potential at point a due to and is given as:
So, (Since, is negative)
Hence, the potential at a due to and is equal to 0 V.
