1.	On increasing the length of the tube of the tube of a compound microscope its magnifying power(A) decreases(B) increases(C) becomes zero(D) does not change
Answer» The correct option is (A) decreases. Magnifying Power (MP) = v/u x D/u_e, L = v + \|u_e\|, if L increases, u_e increases. Hence, When length of microscope tube increase, magnifying power gets decreased.

Answer»

The correct option is (A) decreases.

Magnifying Power (MP) = v/u x D/u_e,

L = v + |u_e|, if L increases, u_e increases.

Hence, When length of microscope tube increase, magnifying power gets decreased.
