Question

an observer moves towards a stationary plane mirror at a speed of 4ms. with what speed will his image appears to move towards him

Answer 1

$\huge\underline\green{\sf Answer}$

$\large{\boxed{\sf Velocity\:w.r.t\:Observer=8 m/s}}$

$\huge\underline\green{\sf Solution :-}$

If a observer is moving towards a plane mirror, the image of his right hand appears to be the left hand of the image

.Suppose, the velocity of the observer is ‘v’ towards the mirror. In the mirror, the image velocity is’(-v)’.

The image velocity w.r.t observer is :-

V = 4 m/s

-V = - 4 m/s

$\small{\boxed{\sf Velocity\:of\:image\:w.r.t\:observer = velocity\:of\:object - velocity\:of\:image}}$

$\large{\sf velocity\:w.r.t\:to\:observer = V - (-V)}$

$\large\implies{\sf 4 -(-4)}$

$\large{\boxed{\sf Velocity\:w.r.t\:Observer= 8 m/s}}$
