Question

State and explain the charge by mass ratio e/ m for electron?​

Answer 1

Answer:

The CODATA recommended value is −e/me = −1.75882001076(53)×1011 C⋅kg−1. CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used. There are two other common ways of measuring the charge-to-mass ratio of an electron, apart from Thomson and Dunnington's methods.

SI unit: kg/C

In SI base units: kg⋅A-1⋅s-1

Common symbols: m/Q
