So the following question was given in the JEE Mains 2016 conducted throughout India on 3rd April.
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
(1) 10 times taller (2) 10 times nearer (3) 20 times taller (4) 20 times nearer
The question has created a lot of controversy as many of the famous physics teachers of India have different opinions. Some go with the third and some with the fourth one. I am looking for a second opinion regarding the answer.
