Match the corresponding entries of column-1 with column-2 (Where m is the magnification produced by the mirror): Column-1: (P) m = −2 (Q) m = −1/2 Column-2: (A) Convex mirror (B) Concave mirror

1. P → B and C, Q → B and C, R → B and D, S → A and D
2. P → A and C, Q → A and D, R → A and B, S → C and D
3. P → A and D, Q → B and C, R → B and D, S → B and C
4. P → C and D, Q → B and D, R → B and C, S → A and D

Correct answer: P → C and D, Q → B and D, R → B and C, S → A and D

Solution

For P (m = -2), the negative sign indicates an inverted image, which is possible with a concave mirror (C) when the object is between the center of curvature and the focus. For Q (m = -1/2), the negative sign again indicates an inverted image, which is possible with a concave mirror (D) when the object is beyond the center of curvature. Thus, the correct matching is P → C and D, Q → B and D.
