Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ f

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ fD

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ fD

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ fD )

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ fD )30 = m

Correct option isA5Given, Magnification,M=30Focal length, f=5 cmFinal distance, D=25 cmIn a compound microscope, M=m o ×m e Thus,30 = m o (1+ fD )30 = m o
