3cm
6cm
\(4\sqrt{2}\) cm
\(3\sqrt{3}\) cm
\(6\sqrt{3}\) cm
Correct answer is E
\(\frac{r}{6} = \sin 60 \)
\(r = 6 \sin 60\)
= \(6 \times \frac{\sqrt{3}}{2}\)
= \(3\sqrt{3}\)
Chord = 2r = \( 2 \times 3\sqrt{3}\)
= \(6\sqrt{3}\)
0.01Ω
0.02Ω
50Ω
100Ω
150Ω
Correct answer is D
\(X_c=\frac{1}{2\pi{fc}}\)=\(\frac{1}{2\times\pi\times\frac{200}{\pi}\times 25\times 10^{-6}}=\frac{10^6}{10^4}\)=100 Ω
8 x \(10^{6}\)
4 x \(10^{6}\)
3 x \(10^{-4}\)
2 x \(10^{-4}\)
5 x \(10^{-7}\)
Correct answer is B
\(E= \frac{F}{O}= \frac{40}{1\times10^{-5}}=4 \times10^{6}\)
The current in a series R-L-C circuit attains its maximum value when the
Impedance is greater than the capacitive reactance
