Answer 2

Answer:

f= +10 cm, u= -25 cm and ho= 5 cm

1/f = 1/v – 1/u

1/v = 1/10 -1/15

1/v = 3/50

V = 50/3 cm.

The image is real and inverted at a distance of 16.7 cm from the lens on opposite side.

Magnification (m) = hi/h0= v/u

hi /5 =16.7/-25

hi = -10/3 cm. image is inverted and diminished.
