Question

a 5 centimetre tall object is placed on the principal axis of a convex lens of focal length 50 cm at a distance of 40 cm from it. Use lens formula to find the nature and position of the image​

Answer 1

Answer:

f=50cm ,u=90cm and v=?

Explanation:

1/v=1/f-1/u

1/v=-1/50-(-1/90)

1/v=-9+5/450

1/v=-4/450

v=-450/4

so, Image is behind the convex lens
