A plane mirror is placed at origin parallel of y-axis, facing the positive x-axis. An object starts from (2m, 0, 0) with a velocity of `(2hat(i)+2hat(j))m//s`. The relative velocity of image with respect to object is along

Text Solution

Verified by Experts


The relative velocity of image with respect to object along normal =` -4 hati `The relative velocity of image with respect to object along plane of mirror = 0.
Hence the relative velocity of image with respect to object = `4hati`.
