Question

A chemist in a galaxy far, far away performed the Millikan oil drop experiment and got the following results for the charges on various drops. Use these data to calculate the charge of the electron in zirkombs. a. 2.56 × 10⁻¹² zirkombs b. 3.84 × 10⁻¹² zirkombs c. 7.68 × 10⁻¹² zirkombs d. 6.40 × 10⁻¹³ zirkombs

Answer 1

The charge of the electron is:
a. 2.56 × 10⁻¹² zirkombs
b. 3.84 × 10⁻¹² zirkombs
c. 7.68 × 10⁻¹² zirkombs
d. 6.40 × 10⁻¹³ zirkombs

To calculate the charge of the electron in zirkombs using the given data, we can use the formula:

Charge of the electron = (Charge on the oil drop) / (Number of excess electrons on the drop)

Let's calculate the charge of the electron for each option:

a. Charge of the electron = (2.56 × 10⁻¹² zirkombs) / (1 excess electron)
Charge of the electron = 2.56 × 10⁻¹² zirkombs

b. Charge of the electron = (3.84 × 10⁻¹² zirkombs) / (1 excess electron)
Charge of the electron = 3.84 × 10⁻¹² zirkombs

c. Charge of the electron = (7.68 × 10⁻¹² zirkombs) / (1 excess electron)
Charge of the electron = 7.68 × 10⁻¹² zirkombs

d. Charge of the electron = (6.40 × 10⁻¹³ zirkombs) / (1 excess electron)
Charge of the electron = 6.40 × 10⁻¹³ zirkombs
