A pinhole camera is placed 300m in front of a building so that the image is formed on a screen 5cm from the the pinhole. If the image is 2.5cm high, the height of the building will be
A
25m
B
50m
C
100m
D
150m
Ask EduPadi AI for a detailed answer
Correct Option: D
==> (\frac{v}{u}) = (\frac{hi}{ho})
==> (\frac{5}{300}) = (\frac{2.5}{ho})
= 150m
