\(\frac{1}{2}\)W
\(\frac{2}{3}\)W
W
2w
3W
Correct answer is E
E = \(\frac{1}{2} Cr^2 = \frac{1}{2}(C-1 + C_2)V^2 = (3C_1)V^2\)
= 3(\(\frac{1}{2}C_1v^2\)) = 3W
4.9 x 10-9N
1.3 x 10-6N
6.6 x 10-8N
6.6 x 10-6N
2.6 x 10-9N
Correct answer is D
F = \(\frac{Gm_1m_2}{r^2} = \frac{6.6 \times 10^{-11} \times 80 \times 50}{0.2 \times 0.2}\)
= 6.6 x 10-6N
450
0.9
900
567
43
Correct answer is C
x = 2\(\pi f L = 2\pi \times \frac{500}{\pi} \times 0.9\)
= 900\(\Omega\)
