Question

derive the relation between joule and erg​

Answer 1

Answer:

The erg is a unit of energy equal to 10−7 joules (100 nJ). It originated in the centimetre–gram–second (CGS) system of units. It has the symbol erg. The erg is not an SI unit.

Answer 2

Explanation:

Joule is the SI unit of energy while erg is the cgs unit of energy.

1 Joule of Energy = 1 Newton x 1 metre

1 erg= 1 dyne x 1 cm

1 joule= 1 newton x 1 metre=105 dynes x 102 cm=107 erg

1 J = 107 erg

Therefore, 1 Joule is equal to 107 erg
