Here’s a trick to really understand what coulomb’s law is. You see, if you measure the area of a circle, it’s always equal to the circle’s radius. If you measure two circles, they’re always equal. That’s coulomb’s law.
You might think coulombs law doesn’t apply to circles. Well, not exactly, it does. But you can apply coulombs law to circles on two different axes.
A circle is a circle in the plane of the sky. You look at a circle in the sky and then look at two points on the circle. If you look at two points on the circle then you see two circles. If the distance between the two points is a function of the distance from one point to the other, it will be a square. That’s coulombs law.
The number of squares in a circle is known as its radius. You can calculate that by looking at two points on the circle and then calculating the distance between the two points. A circle has four sides and three angles. Since the distance between points on your circle is a function of the distance from the two points, it will be a square. You can also look at a circle in the sky and find out the number of sides by looking at two points and then calculating the angle between them.
The number of sides in a circle is known as its radius. The number of angles in a circle is also known as its arc length. To find the arc length, you have to find the distance between two points on the circle, called the centers. The radius of a circle is the distance between the centers, so the arc length of a circle is the distance between the centers divided by the radius.
If you’ve ever been outside and seen a beautiful vista, you know that a circle is a pretty good approximation of a sphere. The radius and arc length of a sphere are not the same. While a circle has a radius of one, a sphere has a radius of infinity. So, if you know the radius you can solve for the arc length.
If you know the radius, you can solve for the arc length using the Pythagorean theorem.
The problem is that the data below doesn’t really tell us which circle to use. The problem is that the data is pretty misleading, because we don’t know the arc length of a sphere because the arc length of a circle is much smaller than the radius of the sphere. But a circle can have a radius of infinity, so you know the radius of a sphere. But a circle can also have a radius of one, so you need to know the radius before you can use it.
