Q. The seperation between the objective and the eye piece of a compound microscope can be adjusted between 9.8 cm to 11.8 cm . Focal length of the objective and the eyepiece are 1.0 cm and 6 cm respectively . Eyepiece is movable and image is always needed at 24 cm from the eye . D= 24 cm . Find the minimum and maximum magnification which can be produced by the microscope.
(A) the minimum magnifcation is 20 and corresponds to the separation 9.8 cm between lenses.
(B)  the minimum magnifcation is 20 and corresponds to the separation 11.8 cm between lenses.
(C)  the minimum magnifcation is 30 and corresponds to the separation 9.8 cm between lenses.
(D)  the minimum magnifcation is 30 and corresponds to the separation 11.8 cm between lenses.
