Question

A plane mirror is placed along the x-axis facing negative y-axis. The mirror is fixed. A point object is moving with $3 \hat { i } + 4 \hat { j }$ in front of the plane mirror. The relative velocity of image with respect to its object is :

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

Velocity of object,

Velocity of image, $\overrightarrow { \mathrm { v } } _ { \text {image } } = 3 \hat { \mathrm { i } } - 4 \hat { \mathrm { j } }$

Relative velocity of image with respect to its object
