A) Zero as r increases for r < R, increases as r increases for r > R
B) Decreases as r increases for r < R and for r > R
C) Increases as r increases for r < R and for r > R
D) Zero as r increases for r < R, decreases as r increases for r > R
Correct Answer: D
Solution :
[d] |
\[{{E}_{inside}}=0\] |
\[{{E}_{surface}}=\frac{kQ}{{{R}^{2}}}=\max .\] |
\[{{E}_{outside}}=\frac{kQ}{{{r}^{2}}}\] |
\[E\propto \frac{1}{{{r}^{2}}}\] |
