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.

    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
