FAQs
Question: What is the difference between electric potential and electric potential energy? Answer: Electric potential refers to the potential energy per unit charge at a point in an electric field, while electric potential energy is the total energy a charge has due to its position in the field.
Question: How do capacitors behave in series and parallel circuits? Answer: In series, the total capacitance decreases, while in parallel, the total capacitance increases. Understanding these configurations is essential for circuit analysis.

Q. If two point charges, +Q and -Q, are separated by a distance d, what is the magnitude of the electric field (E) at the midpoint?
A.
E = 0
B.
E = k * Q / (d/2)^2
C.
E = k * Q / d^2
D.
E = k * Q / (d^2/4)
Solution
At the midpoint, the electric fields due to both charges cancel each other out, resulting in E = 0.
