    If the circumference of a sphere is 2 m, then capacitance of sphere in water would be

    A) 2700             

    B) 2760

    C) 2780                             

    D) 2800

    Correct Answer: D

    Solution :

    Given, circumference \[2\pi r=2\] Now, capacitance of a sphere \[=4\pi {{\varepsilon }_{0}}r\] \[\therefore \]  \[C=4{{\varepsilon }_{0}}\] Capacitance of sphere in water = KC \[=K(4\,\,{{\varepsilon }_{0}})=80\times 4\times 8.85\times {{10}^{-12}}\] [As \[{{K}_{water}}=80\]] \[\simeq 2800pF\]
