Options

A. of microscope increases and of telescope decreases.
B. of microscope and telescope both increases.
C. of microscope and telescope both decreases.
D. of microscope decreases and of telescope increases.

Answer

A, C, D

Explanation

M.P. of microscope = `(LD)/(f_of_e)` . In this, if only ) increases and other remains constant then M. decreases.
M.P. of telescope = `(f_o)/(f_e)`. In this, if `f_0` increase with same `f_e`, then M.P. increases.
