Question

1 Joule = ________________ Erg.

  1. 10000000
  2. 1000000
  3. 100000
  4. 10000

Hint:

1 Joule is equal to 10000000 erg.

The correct answer is: 10000000


    Joule is the SI unit and erg is the CGS unit of energy. Joule is Newton-meter whereas erg is dyne-centimeter. Therefore, as 1 Newton is 100000 dyne and 1 meter is 100 cm; 1 Joule will be equal to 10000000 dyne-cm i.e. 10000000 erg.
