    Correct Option - 4


    Detailed Solution:

    ω = 2 π f ⇒ ω = 100 π

    Z = R 2 + X L - X C 2

    = 10 2 + ω L - 1 ω C 2

    = 100 + 100 π × 50 π × 10 - 3 - 1 100 π × 10 3 π × 10 - 6 2

    = 100 + ( 5 - 10 ) 2

    = 100 + 25

    Z = 5 5 Ω

T = 2π√ (l/g) ⇒ g = 4π²l/T²
Percentage error: Δg/g = Δl/l + 2 (ΔT/T) = (0.1/10.0) + 2 (0.005/0.5) = 0.03
Percentage error = (Δg/g) × 100 = 3%
ω = 2πf = 100π rad/s
i_rms = i? /√2
While current changes from its maximum to its rms value, its phase changes by π/4 rad.
t = (π/4)/ω = π/ (4 × 100π) = 2.5 × 10? ³ s = 2.5ms.
