An object is placed at 5 cm in front of a concave mirror with a radius of curvature of 20 cm. The distance of the image from mirror and its nature are
- A 10 cm, virtual and erect
- B 10 cm, real and inverted
- C 15 cm, real and inverted
- D 3.3 cm, virtual and erect
Answer & Solution
Correct Answer
(A) 10 cm, virtual and erect
Step-by-step Solution
Detailed explanation
\(f = R/2 = -20 \text{ cm}/2 = -10 \text{ cm}\) \(1/f = 1/u + 1/v\) \(1/(-10) = 1/(-5) + 1/v\) \(1/v = 1/(-10) - 1/(-5) = -1/10 + 1/5 = 1/10\) \(v = 10 \text{ cm}\) Nature: virtual and erect (since \(v\) is positive)
