Q. British Scientist JJ Thomson was awarded Nobel prize in Physics in 1906 for discovery of which of the following particle?
Answer: Electron
Notes: British physicist J.J. Thomson was awarded the Nobel Prize in Physics in 1906 for his discovery of the electron. The electron was the first subatomic particle to be found. Thomson discovered the electron while experimenting with cathode rays. He noticed that the rays bent when exposed to electrical and magnetic fields. This led him to believe that the rays were made of tiny particles with a negative charge.  Thomson's discovery of the electron changed atomic theory. Before this, it was believed that the atom was the smallest unit of matter and could not be divided into smaller particles. The discovery of the electron proved that this theory was wrong.
