Electric Potential between two point charges

Click For Summary
SUMMARY

The discussion focuses on calculating the electric potential between two point charges, Q1 = +5.00 nC and Q2 = −3.00 nC, separated by 35.0 cm. The electric potential at the midpoint between the charges is derived using the formula V = k * (Q1/r1 + Q2/r2), where k is Coulomb's constant. Additionally, the energy required to bring an electron from infinity to this point is calculated using the formula PE = k * (Q1 * Q2) / r. The specific values lead to a definitive understanding of electric potential in electrostatics.
