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.

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.

$U=\frac{1}{4\mathrm{Ï€}{\mathrm{Î\mu }}_0}\left(\frac{(1\mathrm{nc}×(−2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}+\frac{(1\mathrm{nc}×(−2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}+\frac{(−2\mathrm{nc}×(−2.0\mathrm{nc}\left)\right)}{3.0\mathrm{cm}}\right)$

Performing the mathematics, we observe that

$U=0\mathrm{J}$

$U=0$ .
