Question

given that a is the average (arithmetic mean) of the first nine positive multiples of six and b is the median of the first twelve positive multiples of six what is the ratio of a to b?

Answer 1

The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. Since the value of the elementary charge is roughly 1.602 x 10-19coulombs (C), then the charge of the electron is -1.602 x 10-19 C.
