1.	a car has a driving mirror of focal length 40 cm another car of same dimensions is 12 metres away from the mirror of the first car the position of the second car as seen in the mirror of first car
Answer» ANSWER: f = (+)40 CM u = (-)12 cm v = X cm 1/f = 1/v + 1/u 1/40 = 1/v - 1/12 1/v = 1/40 + 1/12 1/v = 3+10/120 1/v = 13/120 v = 9.23 cm

a car has a driving mirror of focal length 40 cm another car of same dimensions is 12 metres away from the mirror of the first car the position of the second car as seen in the mirror of first car

Answer»

ANSWER:

f = (+)40 CM

u = (-)12 cm

v = X cm

1/f = 1/v + 1/u

1/40 = 1/v - 1/12

1/v = 1/40 + 1/12

1/v = 3+10/120

1/v = 13/120

v = 9.23 cm
