# A magnifying glass problem

## Homework Statement

A lens having a focal length 50 cm is used as
a simple magnifier.

What is the angular magnification obtained
when the image is formed at the normal near
point (25 cm)?

## Homework Equations

1) m = N/d, where d is distance of object

2) m = 1 + N/f

I don't really get what do they want as the answer.

Also, there are two equations, which one do I use?

THanks! :)
