Question

In an oil drop experiment, the following charges (in arbitrary units) were found on a series of oil droplets 4.5 × 10−18, 3.0 × 10−18, 6.0 × 10−18, 7.5 × 10−18, 9.0 × 10−18. The charge on electron (in the same unit) should be

Options

A.3.0 × 10−18
B.9.0 × 10−18
C.1.5 × 10−18
D.1.6 × 10−19

Solution

Charge on electron = HCF of charges in oil droplets = 1.5 × 10–18 unit
