Question

An object of height 6 cm is placed perpendicular to the principal axis of a concave lens of focal
length 5cm. Use lens formula to determine the position, size and nature of the image if distance
the object from the lens is 10 cm.

Answer 1

Answer:

lens formula=

1/f=1/v-1/u

1/5=1/v-1/-6

1/v=1/5+1/-6

1/v=6-5/30

1/v=1/30

v=30/1

v=30cm

m=v/u

m=30/-6

m=-5

the nature of the Image is real
