    Variation of electric potential V as a function of distance x through five regions on X-axis. Which of the following is true regarding electric field E in these regions                

    A)  \[\sqrt{2}R\sqrt{\eta {{T}_{0}}}\]

    B)  \[2R\sqrt{\eta {{T}_{0}}}\]

    C)  \[2\sqrt{2}R\sqrt{\eta {{T}_{0}}}\]

    D)  \[R\sqrt{\eta {{T}_{0}}}\]

    Correct Answer: B

    Solution :

                    Consider the potential (V) versus (X) graph. We can find the electric field by using \[{{t}_{2}}\] \[2g({{t}_{1}}+{{t}_{2}})\] \[\frac{g}{4}{{({{t}_{1}}+{{t}_{2}})}^{2}}\] \[g/4({{t}_{1}}{{t}_{2}})\] \[2g{{\left( \frac{{{t}_{1}}+{{t}_{2}}}{4} \right)}^{2}}\] \[R/4\] Thus,     \[R/2\]  and \[R/8\]
