  • question_answer The capacitance of a spherical conductor with radius 1 m is:

    A)  \[9\times {{10}^{-9}}F\]      

    B)  \[1\,\mu F\]

    C)  \[2.5\times {{10}^{-10}}F\]    

    D)  \[1\times {{10}^{-6}}F\]

    Correct Answer: C

    Solution :

     The capacitance of spherical conductor is given by          \[C=4\pi {{\varepsilon }_{0}}r\] Here: \[r=1\text{ }m,\,4\pi {{\varepsilon }_{0}}=\frac{1}{9\times {{10}^{9}}}\] \[C=\frac{1}{4\times {{10}^{9}}}\times 1\] \[C=2.5\times {{10}^{-10}}F\]
