Answer 2

Answer:

Electrostatic energy is stored in the capacitor is (E) IS $25*10^{-9} joules$

Explanation:

TO FIND :

     How much electrostatic energy is stored in the capacitor.

GIVEN:

   The capacity of capacitor is (C)  $20PF$

             $20 PF = 20*10^{-12}$

     Voltage of a battery is (V)  $50V$

    Electrostatic energy is stored in the capacitor is (E)

                                   $E=\frac{1}{2}CV^{2}$

                                    $E=\frac{1}{2} * (20*10^{-12} )*50^{2}$

                                    $E=10*10^{-12} *2500$

                                     $E=25000*10^{-12} \\E=25*10^{-9}$

   Electrostatic energy is stored in the capacitor is (E) IS $25*10^{-9} joules$
