A 4.0cm tall object is placed 50cm away from a converging lens of focal length 20 cm. What is the nature and location of the image?
Uaing lens formula
1/f = 1/v - 1/u
1/20 = 1/v + 1/50
v = 33.33 cm
======
Image height
h' = h v/u = 4 * 33.33 / 50 = 2.667 cm
======
Image must be inverted and real
======
Comment before rate in case any doubt, will reply for sure.. Goodluck
