There is a concept that if unit of a physical quantity is large then the multiplier of the unit becomes less while expressing any fixed magnitude. If in a new system of unit, unit of time is 0.5 second and the unit of length is 4 metre. Answer the following questions.
The value of speed of light becomes (c is intial value) :

A

c

B

`c//2`

C

`c//4`

D

`c//8`

Text Solution

Verified by Experts

The correct Answer is:
b
Since, `c=3xx10^(8) m//s`
Hence, `3xx10^(8) m//s=n_(2) (8 m s^(-1))`
Hence, `n_(2)=((3xx10^(8))/8)`
