Question

In the Bohr’s model of hydrogen atom, the electrons moves around the nucleus in a circular orbit of a radius 5 × 10^–11metre. It’s time period is 1.5 × 10^–16sec. The current associated is

• A. Zero
• B. 1.6 × 10^–19A
• C. 0.17 A
• D. 1.07 × 10^–3A

Answer 1

Answer: (D)

1.07 × 10^–3A

Answer 2

$i = \frac { q } { T } = \frac { 1.6 \times 10 ^ { - 19 } } { 1.5 \times 10 ^ { - 16 } } = 1.07 \times 10 ^ { - 3 } \mathrm {~A}$
