Question

A simple magnifying lens is used in such a way that an image is formed at 25 cm away from the eye. In order to have 10 times magnification, the focal length of the lens should be

  1. 5 cm    
  2. 2 cm    
  3. 25 mm    
  4. 0.1 mm    

The correct answer is: 5 cm


    fraction numerator D over denominator F end fraction or fraction numerator 25 over denominator F end fraction
