A)
B)
C)
D)
Correct Answer: C
Solution :
[C] \[\phi =\vec{E}.\vec{d}s\] Since r << R so we can consider electric field is constant throughout the surface of smaller ring, hence \[\phi \propto E\propto \frac{x}{{{({{R}^{2}}+{{x}^{2}})}^{3/2}}}\] So, the best represented graph is C.You need to login to perform this action.
