Question

How much distance an electron revolving in 3rd orbit of He+ ion will travel in one second

Options

A.1.458 × 106 m
B.3.28 × 106 m
C.4.862 × 105 m
D.2.917 × 106 m

Solution

$V_{n,z} = 2.188 \times 10^{6} \times \frac{z}{n} = 2.188 \times 10^{6} \times \frac{2}{3} = 1.459 \times 10^{6}\text{ m/s}$

∴ Distance travelled by electron in 1 second = 1.459 × 106 m
