100 cm 25 cm 2.5 cm 0.01 cm
I gave my students this multiple choice question: A microscope magnifies an object with 50x magnification. How long is the object if the image appears to be 0.5 cm long?

Only one answer is correct among these 4 choices:
- 100 cm
- 25 cm
- 2.5 cm
- 0.01 cm

Could you tell me which one is correct?

0.01 cm
