The velocity of image when object and mirror both are moving towards each other with velocities 4 ms⁻¹ and 5 ms⁻¹ respectively, is
Options
(a) (-14ms⁻¹)
(b) 15ms⁻¹
(c) (-9ms⁻¹)
(d) 14ms⁻¹
Correct Answer:
(-14ms⁻¹)
Explanation:
ʋ(OM) = Velocity of object with respect to mirror = -ʋ(IM)
(Here, -ʋ(IM) = velocity of image with respect to mirror)
ʋ(o) – ʋ(M) = -[ʋ(I) – ʋ(M)]
4 ms⁻¹ – (-5 ms)⁻¹ = -ʋ(I) + (-5 ms⁻¹)
ʋ(I) = – 14 ms⁻¹
