Question

10. An object is placed at 0.06 metre from a
convex lens of focal length 0.1 metre, the
position of the image will be *
(1 Point)
15 cm
-15 cm
7.5 cm
-30 cm​

Answer 1

Answer:

-15 cm

Explanation:

1/f = 1/v - 1/u

1/f +1/u= 1/v

focal length for convex lens is positive and u( object dist) is always negative

thus:

1/f +1/(-u) = 1/v

f= 0.1 m that is 10 CM

u= 0.06 m that is 6 CM

substitute the values in formula

1/10+1/(-6) = 1/v

3-5/30 = 1/v

-2/30= 1/v

-1/15=1/v

-15=v

v= -15 cm
