Answer:
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
