Three equal point charges, each with charge 1.05 μCμC , are placed at the vertices of an equilateral triangle whose sides are of length 0.500 mm . What is the electric potential energy UUU of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)

The value is

Explanation:

From the question we are told that

The value of charge on each three point charge is

The length of the sides of the equilateral triangle is

Generally the total potential energy is mathematically represented as

=>

Here k is coulomb constant with value

so easy. just google the electromagnetic waves and it’ll pop up.
