Question

What is the e/m ratio of an electrone ?​

Answer 1

Answer:

The ratio of the charge of an electron to the mass of an electron. The currently accepted value for e/m is 1.758820 × 1011 C/kg.

Answer 2

AnswerThe 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.

➡️In SI base units: kg⋅A-1⋅s-1

➡️SI unit: kg/C

➡️Common symbols: m/Q
