FAQs on Important formulas of potential in electrostatics Video Lecture - Basic Physics for IIT JAM

1. What is the formula for the electric potential due to a point charge?
Ans. The formula for the electric potential due to a point charge is given by V = kQ/r, where V is the electric potential, k is the electrostatic constant (9 x 10^9 Nm^2/C^2), Q is the charge, and r is the distance from the point charge.
2. How can I calculate the electric potential due to multiple point charges?
Ans. To calculate the electric potential due to multiple point charges, you need to calculate the electric potential due to each individual charge and then add them together. The formula for the electric potential due to multiple point charges is V = ∑ (kQi/ri), where V is the total electric potential, k is the electrostatic constant, Qi is the charge of each point charge, and ri is the distance from each point charge.
3. What is the formula for the electric potential due to a charged sphere?
Ans. The formula for the electric potential due to a charged sphere is V = kQ/R, where V is the electric potential, k is the electrostatic constant, Q is the charge of the sphere, and R is the radius of the sphere.
4. How do I calculate the electric potential at a point between two charges?
Ans. To calculate the electric potential at a point between two charges, you need to find the electric potential due to each charge separately and then add them together. The formula for the electric potential at a point between two charges is V = (kQ1/r1) + (kQ2/r2), where V is the electric potential, k is the electrostatic constant, Q1 and Q2 are the charges, and r1 and r2 are the distances from each charge.
5. What is the formula for the electric potential energy of a system of charges?
Ans. The formula for the electric potential energy of a system of charges is U = (1/2) ∑ (kQiQj/rij), where U is the total electric potential energy, k is the electrostatic constant, Qi and Qj are the charges, and rij is the distance between each pair of charges.
