Explanation:
Imagine you have three tiny little balls, each with a positive or negative charge. These balls are located at the corners of an equilateral triangle, which means that all three sides of the triangle are the same length.
Now, something really cool happens when you have charges in close proximity to each other - they start to interact. The charged particles will either push away or pull towards each other, depending on whether they have the same or opposite charges. And since the particles are located at the corners of an equilateral triangle, the forces between them will be balanced and in equilibrium, which means that the net force on each particle is zero.
This is known as electrostatic equilibrium, and it's a really important concept in physics. It's used to explain a lot of natural phenomena, like why our hair stands up when we rub a balloon on it.
