A) zero
B) \[\frac{2\lambda R}{{{\varepsilon }_{0}}}\]
C) \[\frac{2\lambda \sqrt{{{R}^{2}}-{{y}^{2}}}}{{{\varepsilon }_{0}}}\]
D) \[\frac{\lambda \sqrt{{{R}^{2}}+{{y}^{2}}}}{{{\varepsilon }_{0}}}\]
Correct Answer: C
Solution :
[c] Charge on length \[AB=2\sqrt{{{R}^{2}}-{{y}^{2}}}\times \lambda \] Electric flux \[\oint{\vec{E}.\overrightarrow{ds}}=\frac{2\lambda \sqrt{{{R}^{2}}-{{y}^{2}}}}{{{\varepsilon }_{0}}}\]You need to login to perform this action.
