The mean distance of sun from the earth is `1.5xx10^8km`. The time taken by light to reach earth from the sun is

A

`0.12min`

B

`8.33min`

C

`12.5min`

D

`6.25min`

Text Solution

Verified by Experts

The correct Answer is:
B
`t=d/c=(1.5xx10^8xx10^3)/(3xx10^8)=500sec`
`=(500)/(60)=(50)/(6)=8.3min`
