  • question_answer
    How much charge should be placed on a capacitance of 25 pF to raise its potential to \[{{10}^{5}}V\]?

    A) \[1\mu C\]

    B) \[1\centerdot 5\mu C\]

    C) \[2\,\,\mu C\]

    D) \[2\centerdot 5\mu C\]

    Correct Answer: D

    Solution :

    As \[q=CV=25\times {{10}^{-12}}\times {{10}^{5}}=2\,.\,5\,\mu C\]
