Explanation / Answer

Given,

h = 3 cm ; o = 50 cm ; f = -25 cm

A)We know from lens equation

1/f = 1/i + 1/o

i = o x f/(o - f)

i = 50 x -25/(50 + 25) = -16.67 cm

Hence, i = -16.67 cm (upto two decimal places)

B)magnification is:

M = -i/o = h'/h

h' = M h

M = -(-16.67)/50

h' = 0.3334 x 3 = 1.0002 cm

Hence, h' = 1.00 cm (upto two decimal places)
