Question

Which of the following are the properties of an electron?
1. Electron is a constituent of cathode ray
2. Electron is a negatively charged particle
3. The mass of the electron is equal to the mass of the proton
4. Electron is deflected by the electric field but not by magnetic field
Select the correct answer using the code given below:

• A. 1 and 2 only
• B. 1, 2 and 3
• C. 3 and 4
• D. 1 and 4

Answer 1

The correct option is A 1 and 2 only

Properties of an electron are
1. Electron is a constituent of cathode ray
2. Electron is a negatively charged particle
3. The mass of the electron is less than mass of the proton
4. Electron can be deflected by the electric field and magnetic field.

So option A is correct.
