Question

The ratio of Sl unit to CGS unit of the force constant (k) is * 1





​

Answer 1

Answer:

S.I. unit of thrust (or force) is Newton (N) and C.G.S. unit is dyne.

We know that 1=N=10

5

dynes

Ratio of S.I. unit of force to C.G.S. unit is

N:dyne=10 ^5 :1

Answer 2

Dyne is CGS unit. Newton is in SI unit. 

Therefore by definition of force we have: f=ma [2nd Law] 

[MLT^-2] 

Now ratio of si to cgs: 

metres x kilogram x seconds / centimeters x gram x seconds 

100cm x 1000 gm / 1 cm x 1 gm 

Therefore, ratio is 10^5 : 1

hope it help you dear....
