12th Class Physics Electrostatics & Capacitance Question Bank Case Based (MCQs) - Electrostatic Potential and Capacitance

  • question_answer
    Metallic sphere of radius R is charged to potential V. Then charge q is proportional to:

    A) V                                 

    B) R

    C) Both (a) and (b)     

    D)   None of these

    Correct Answer: C

    Solution :

    (c) Both (a) and (b) As charge, \[q=CV=\left( 4\pi {{\varepsilon }_{0}}R \right)V\] \[\therefore \]q depends on both V and R.
