An equiconvex lens of glass of focal length `0.1 ` metre is cut along a plane perpendicular to principle axis into two equal parts. The ratio of focal length of new lenses formes is

A

`1:1`

B

`1:2`

C

`2:1`

D

`2:(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Focal length of each part of lens becomes `0.2` m.
`:.(f_(1))/(f_(2))=(0.2)/(0.2)=1:1`
