An observer looks at a distant tree of height 10 m with a telescope of magnifying power of 20 . To the observer, the tree appears as

Options

  1. A20 times taller.
  2. B20 times nearer.
  3. C10 times taller.
  4. D10 times nearer.

Correct answer

B. 20 times nearer.

Step-by-step solution

Angular magnification of the telescope is 20 so now the tree will subtend a larger angle at the observer's eye and hence appears 20 times nearer
