Three charged particles are positioned in the xy plane: a 50-nc charge at y = 6 m on the y axis, a −80-nc charge at x = −4 m on the x axis, and a 70-nc charge at y = −6 m on the y axis. what is the electric potential (relative to a zero at infinity) at the point x = 8 m on the x axis?

V = 48 Volts

Explanation:

Since we know that electric potential is a scalar quantity

So here total potential of a point is sum of potential due to each charge

It is given as

here we have potential due to 50 nC placed at y = 6 m

Now potential due to -80 nC charge placed at x = -4

Now potential due to 70 nC placed at y = -6 m

Now total potential at this point is given as
