Electrostatic Potential Energy Video Lecture | Physics Class 12 - NEET

Ans. Electrostatic potential energy is the energy stored in a system of charged particles due to their positions relative to each other. It is the work required to bring a test charge from infinity to a point in the electric field created by the charged particles.

Ans. The electrostatic potential energy can be calculated using the formula U = k * (q1 * q2) / r, where U is the electrostatic potential energy, k is the electrostatic constant (9 × 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

Ans. Yes, electrostatic potential energy can be negative. If the charges involved have opposite signs, the potential energy is negative, indicating that work would be done by the system to bring the charges closer together. If the charges have the same sign, the potential energy is positive.

Ans. The electrostatic potential energy between two charges is inversely proportional to the distance between them. As the distance increases, the potential energy decreases, indicating a weaker interaction between the charges. Conversely, as the distance decreases, the potential energy increases, indicating a stronger interaction.

Ans. Some examples of electrostatic potential energy in everyday life include: - Lightning: The buildup of electrostatic potential energy in storm clouds leads to the discharge of lightning bolts. - Van de Graaff generator: This device accumulates electrostatic potential energy to create static electricity for various experiments. - Capacitors: Capacitors store electrostatic potential energy in electronic circuits, which is then released to power devices. - Photocopiers: Electrostatic potential energy is utilized in the photocopier's process to transfer toner onto paper. - Static cling: When clothes stick together due to static electricity, it is a result of electrostatic potential energy.
