The charge on an electron was discovered by:

A

J.J. Thomson

B

Neil Bohr

C

James Chadwick

D

Millikan

Answer

J.J. Thomson

Explanation

Solution

The specific charge (e/m)( e / m ) on electron was first of all determined by J.J. Thomson. Magnitude of charge on electron =1.6×10−19=1.6 \times 10^{-19} coulomb =4.8×10−10=4.8 \times 10^{-10} e.s.u
