364640 An object is initially at a distance of \(100\,cm\) from a plane mirror. If the mirror approaches the object at a speed of \({5 {~cm} / {s}}\), then after 6 s the distance between the object and its image will be

1 \(60\,cm\)
2 \(140\,cm\)
3 \(170\,cm\)
4 \(150\,cm\)

364641 If an observer is walking away from the plane mirror with \(6\;m{\rm{/}}\sec \). Then the velocity of the image with respect to observer will be

1 \(10\;m{\rm{/}}\sec \)
2 \(12\;m{\rm{/}}\sec \)
3 \(24\;m{\rm{/}}\sec \)
4 \(6\;m{\rm{/}}\sec \)
