C)100 s
D)None are correct.

Question

Quizplus · Accepted Answer

The period of electromagnetic oscillations in an LC circuit can be found using the formula T=2π√(LC). Plugging in the given values, 
T=2π√(10.0μF × 10.0mH)
T=2π√(10 × 10^(-6) F × 10 × 10^(-3) H)
T=2π√(10 × 10^(-5) s^2)
T=2π × 0.01 s
T=0.0628 s or 62.8 ms (rounded to three significant figures)
Therefore, the correct answer is A) 62.8 ms.
