Question

An electron having charge 1.6 × 10-19 C
and mass 9 x 10-31 kg is moving with
4 x 10 ms-' speed in a magnetic field
2 x 10-1 T in a circular orbit. The force
acting on electron and the radius of the
circular orbit will be​

Answer 1

Answer:

No, it does not mean that the electron has a charge 3.2 × 10–19 C less than the charge of a proton. Electrons and Protons have same amount of charge just the nature of charge is different. Electron has negative charge and Proton has positive charge. If we keep an electron and a proton at a distance apart then attractive force will be observed as their nature of charge is different.

Hence, magnitude of charge of both electron and a proton is 1.6 × 10–19 C but nature is opposite.

Explanation: this is perfect answer
