please answer fast​

Answer 1

I think (d) is the answer

Answer 2

Answer:

(A) 5/π×10³ HZ

Explanation:

=>frequency will be maximum at resonant state ,when Xc = XL

So, formula of resonating frequency in LCR circuit is :) F = 1/2π√LC

L = 5MH = 5× 10^-3H

C = 2uf = 2× 10^-6 F

•°• F = 1/2π√ (5*10^-3× 2×10^-6 )

=> F = 1/2π ×10^-4

=> F = 10⁴/2π = 10* 10³/2π

=> F = 5×10³/πHZ

Since , option (A) is correct
