The magnifying power of a telescope can be increased

A

by increasing focal lengths of both length

B

by fiting eyeplace of high power

C

by fiting eye place of low power

D

by increasing the distance of object

Text Solution

Verified by Experts

The correct Answer is:
B

`MP=-((f_(0))/(f_(theta)))` to increase the magnifying we will decreases `f_(0)`
So, we will use eyepiece of high power
