Q 1113745649.     A convex lens has its radii of curvature equal. The focal length of the lens is `f`. If it is divided vertically into two identical plano-convex lenses by cutting it, then the focal length of the plano- convex lens is (`mu` = the refractive index of the material of the lens)

A

`f/2`

B

`2f`

C

`f`

D

`(mu-1)f`

HINT

Use `1/(f) =(mu-1)(1/R_1-1/R_2)`
