Question

If the beams of electrons and protons move parallel to each other in the same direction, then they

• A. attract each other
• B. Repel each other
• C. No relation
• D. Neither attract nor repel

Answer 1

The correct option is B

Repel each other

Step1: Electrons

1. An electron is a negatively charged subatomic particle that can exist in two states: free (not associated with any atom) and attached to the nucleus of an atom.
2. The size of the electron's spherical shell is exactly proportional to the energy contained in the electron.
3. Because the electron is a negatively charged particle, its effective charge is $-1$.

Step2: Protons

1. The positively charged particles are known as protons. A proton is commonly denoted by the letter p, and its charge is $+1$.
2. They move in straight lines and can cast shadows on anything in their way.
3. Electric as well as magnetic forces deflect these positive photons.

Step3: If electron and proton beams move in the same direction, they are said to be parallel.

Protons are positively charged, while electrons are negatively charged. As a result, the currents they carry are in opposite directions. Therefore, they repel each other.

Hence, option B is the right answer.
