1.	What are the S.I. and C.G.S units of work? How are they related? Establish the relationship.
Answer» S.I unit of work is Joule. C.G.S unit of work is erg. Relation between joule and erg : 1 joule = 1N x 1m But 1N = 10⁵ dyne And 1m=100 cm = 10² cm Hence, 1 joule = 10⁵dyne × 10²cm = 107dyne × cm =10⁷erg Thus, 1 Joule = 10⁷ erg

What are the S.I. and C.G.S units of work? How are they related? Establish the relationship.

Answer»

S.I unit of work is Joule.

C.G.S unit of work is erg.

Relation between joule and erg :

1 joule = 1N x 1m

But 1N = 10⁵ dyne

And 1m=100 cm = 10² cm

Hence, 1 joule = 10⁵dyne × 10²cm

= 107dyne × cm =10⁷erg

Thus, 1 Joule = 10⁷ erg
