At what point along the line connecting the two charges is the total electric field due to the two charges equal to zero?      Question # 2 The sum of the charges on both plates of a capacitor is zero. What does a capacitor store?   Ans: The total charge in a capacitor is always zero and in equilibrium with its surroundings. But capacitors do store electric energy. The energy is stored in an electric field. Voltage, when applied between two plates of a capacitor, creates a potential difference between its plates.   Question # 3 (a)    A 20 dB sound is twice as intense as a 10 dB sound, explain it.

If got no answer let me know I will explain it to you in detail.     ·          Version (i.e. 4 bits ) Given  ·          FU=( 8bit) mentioned clearly that 8 bits reserved for future use.  ·          ToS=(4 bit) Because minimum 4 bit required to represent 16 different numbe
