A capacitor is charged by a battery and energy stored is 'U'. Now the battery is removed and the distance between plates is increased to four times. The energy stored becomes

Options

  1. A4 U
  2. BU.
  3. C3 U
  4. D2 U

Correct answer

A. 4 U

Step-by-step solution

As we know energy stored in capacitor is propotional to distance so, after increases the distance energy will be 4U.
