Electromagnetic force is ............. range force (a) Short (b) long (c) medium (d) very short

In physics, there are four fundamental forces; these are the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force. Each of these forces has a specific range over which they can operate effectively.

Let's briefly examine the ranges of each of the four fundamental forces: 1. Gravitational force: This force is long-range, as it acts between any two masses in the Universe, regardless of the distance between them. 2. Electromagnetic force: This force acts between charged particles and is responsible for phenomena such as electricity and magnetism. It is also a long-range force, like the gravitational force. 3. Weak nuclear force: This force is responsible for processes such as radioactive decay, and it acts within very short distances of the order of atomic nuclei. Therefore, it is a short-range force. 4. Strong nuclear force: This force holds protons and neutrons together in atomic nuclei. Like the weak nuclear force, it also acts within very short distances, making it a short-range force as well.

From the information in Step 2, we can see that the electromagnetic force acts between charged particles and is a long-range force in nature, just like the gravitational force. So, the answer is: (b) long
