1.

An object and a plane mirror are shown in figure. Mirror is moved with velocity `V` as shown. The velocity of image is : .A. `2 V sin theta`B. 2 VC. `2 V cos theta`D. none of these

Answer» Correct Answer - A
`vec(V)_(1)=vec(V)_(0)m=` (normal to plane mirror)
`rArr vec(V)_(1)m-vec(V)_(m)=-(vec(V)_(0)-vec(V)_(m))`
`vec(V)_(1)-V sin theta =-(0-V sin theta)`
`V_(1)=2V sin theta`.
