A plane mirrorr 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

Options

A. positive `x-`axis
B. negative `x-`axis
C. positive `y`-axis
D. negative `y`-axis

Answer

B

Explanation

`|vec(V_(0))|=|vec(V_(1))|=sqrt((2)^(2)+(2)^(2))=2sqrt(2)m//s`
Relative velocity of image with respect to object is in negative `x-`direction as shown in figure.
