9 x 10-13m
9 x 10-7m
9 x 10-3m
9 x 107m
Correct answer is B
C = \(\frac {\varepsilon_o\ A}{d}\)
10-2 x 10-6 = \(\frac {9 \times 10 ^{-12}}{d}\) x 10-4
= 9 x 10-7m
200C
50C
12C
0.002C
Correct answer is C
Q = it
= 100 x 10-3 x 2 x 60
= 12C
0.5 \(\Omega\)
1.0\(\Omega\)
2.0\(\Omega\)
4.0\(\Omega\)
Correct answer is C
E = 4 + 2r and E = 2 + 3r
therefore, r = 2\(\Omega\)
