Type: MCQ-numerical-Medium-Class 12
In an atom electrons revolve around the nucleus along a path of radius 0.72 Å making 9.4 × 10¹⁸ revolution per second. The equivalent current is (e = 1.6 × 10⁻¹⁹)
A
2 Å
B
5 Å
C
4 Å
D
8 Å
Correct Answer
Option A
Detailed Explanation
The equivalent current is calculated using the formula I = e × frequency. Substituting the given values, the current is found to be 1.2 Å.
