Question

A 6 cm object is placed perpendicular to the principal axis of a convex lens of afocal length 15 cm. the distance of the object form the lens is 10 cm find the position, size and nature of the image formed, using the lens formula. [v=-30,h’=18] PLEASE ANSWER CORRECTLY AND AS SOON AS POSSIBLE [URGENT]

Answer 1

Answer:

h1= 6 cm, f= 15 cm, u= -10 cm

i/f=1/v-1/u

1/f+1/u=1/v

1/15-1/10=1/v

2-3/30=1/v

-30 cm=v

m=v/u

m=-30/-10

m=3

h2/h1=m

h2/6=3

h2=18cm

Thus, image formed is virtual, erect, magnified and 30 cm away
