Question

The electric potential at a position located a distance of 21.9 mm from a positive point charge of 8.40×10^-9C and 10.3 mm from a second point charge is 1.26 kV. Calculate the value of the second charge. The potential at a position is the sum of the individual contributions to the potential by each of the 2 charges. The sign is important. Calculate the potential due to the first charge. The difference is due to the second charge.

Answer #1

we know the electric potential due to point charges is

The electric potential at a position located a distance of 18.3
mm from a positive point charge of 7.80×10-9C and 12.1 mm from a
second point charge is 1.42 kV. Calculate the value of the second
charge.

The electric potential at a position located a distance of 21.6
mm from a positive point charge of 7.80×10-9C and 14.2 mm from a
second point charge is 1.30 kV. Calculate the value of the second
charge.

The electric potential at a position located a distance of 22.8
mm from a positive point charge of 7.10×10-9C and 13.6
mm from a second point charge is 1.10 kV. Calculate the value of
the second charge.
The answer is NOT -2.56x10^-3C/
