Question

What is the electric potential energy of the group of charges in FIGURE EX25.6?

Short answer

The system's potential energy is $0$.

Step-by-step solution

Step : 1  Definition

Given information:

Charges are $1.0nc$,$-2.0nc$.

Distance between charges are $3.0cm$.

Find:

The objective is to find electric potential energy of the group of charges.

Electron density radiation is the amount of energy required a component discharge will become if it is deposited someplace, including in orbit.

Potential energy of the system.

The gravitational potential of the ensemble is comparable to the actionable from every combination of electrons. The restoring force of interactions involving electrons of the very same indication is optimistic, while the latent heat of communication among charges of the opposite polarity is negatives.

$U=\frac{1}{4\pi {\epsilon }_0}\left(\frac{(1\mathrm{nc}\times (-2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}+\frac{(1\mathrm{nc}\times (-2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}+\frac{(-2\mathrm{nc}\times (-2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}\right)$

Step : 3 Evaluating Potential Energy

Performing the mathematics, we observe that

$U=0\mathrm{J}$

$U=0$ .
