Two point charges, +3.21 µC and -6.75 µC, are separated by 1.13 m. What is the electric potential midway between them?

The electric potential midway between them is -5.64 × 10^4 V

Explanation:

Electric potential is measured in volts or joules per coulomb. It is the amount of work required to move a charge from a reference point to a specific point inside the field.

Electric potential V = Σkq/r

k = coulomb's constant = 9.0x10^9 N-m^2/C^2

q1 = +3.21 × 10^-6 C

q2 = -6.75 × 10^-6 C

r = 1.13/2 = 0.565m

V = kq1/r + kq2/r = (k/r)(q1 + q2)

Substituting the values;

V = (9.0x10^9/0.565)(3.21 - 6.75) × 10^-6

V = -56389.3805309 Volt

V = -5.64 × 10^4 volts

explanation:

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
