Type: MCQ-numerical-Hard-Class 12
A 2.5 cm tall object is placed 27 cm in front of a concave mirror with a radius of curvature of 36 cm. At what distance from the mirror will the screen show a sharp image of the object?
A
18 cm
B
36 cm
C
24 cm
D
54 cm
Correct Answer
Option A
Detailed Explanation
Using the mirror formula 1/f = 1/v + 1/u and f = R/2, we find f = 18 cm. Substituting u = -27 cm, we calculate v = 18 cm. Thus, the screen should be placed at 18 cm from the mirror.
