If the resolution limit of the eye is 1 minute and at a distance `x` km from the eye, two persons stands with a lateral separation of `3m`, then calculate `x` for which the twok persons can be just resolved by the nacket eye.

`10km`

`15km`

`20km`

`30km`

Text Solution

Verified by Experts

(a) `theta=l/r`, where `theta=` 1 minute
`theta=1/(60^(@))=((pi)/180xx1/60)rad` and `l=3m`
`x=r=l/(theta)=(3m)/((pi)/180xx1/60)=10318~~10km`
