Question

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

Solution
Verified by Toppr

Given : u=10 cm f=5 cm ho=6 cm

Using lens formula : 1v1u=1f

1v1(10)=15

v=103=3.33 cm (- sign shows that image is virtual)

Also m=hiho=vu

hi6=10310

hi=+2 cm (+ sign shows that image is erect)
