A single electron has a charge of 2.9×10−15 ZZ . Using zeets and a fictitious unit of mass called the wiggle, ww, the charge-to-mass ratio of an electron is 2.4×106 Z/wZ/w . What is the mass of an electron in wiggles? Express the mass of an electron in wiggles using two significant figures.

Answer:

m = 1.2 10⁻²¹  w

Explanation:

Despite having other units the laws of physics and comply with all inertial systems, so the charge-mass ratio of the electron is the same

                         Rel = e / m

                         m = e / Rel

Where Rel is the ratio, e the charge of the electron and m the masses of the electron

Let's calculate

                        m = 2.9 10⁻¹⁵ / 2.4 10⁶

                       m = 1.2 10⁻²¹  w
