Physics · Electrostatic Potential

हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When an isolated charged capacitor is connected to an identical uncharged capacitor, the total electrostatic energy stored in the two capacitors decreases by \( 50\% \). Reason (R): The total electric charge on the plates of the two capacitors decreases by \( 50\% \) during the sharing process. In the light of the above statements, choose the correct answer from the options given below:

  1. A
    Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. B
    Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. C
    is true but (R) is false.
  4. D
    is false but (R) is true.
View Answer & Solution

Correct answer · Option C

is true but (R) is false.

Explanation

Assertion is true: \( U_f = \frac{1}{2} U_i \), so \( 50\% \) energy is lost as heat/electromagnetic radiation during charge sharing. Reason is false: electric charge is strictly conserved by the conservation of charge; total charge remains \( Q \).
