Question
Derive a relation between the S.I. and C.G.S. unit of force.
Solution
We have Force = Mass × Acceleration
`∴ ("S.I. unit of force")/("C.G.S unit of force")=("kg"xx"ms"^-2)/("g"xx"cm s"^-2)=("kg"/"g")("m"/"cm")=10^3xx10^2=10^5`
∴ S.I. unit of force (Newton) = 105 C.G.S. unit of force (dyne)
Or 1 Newton = 105 dyne.
