Question

An object moves towards a plane mirror with a speed of 10 m/s. The speed of image with respect to object is
Options
o
10 m/s
20 m/s
O 25 m/s
O Zero​

Answer 1

Answer:

20 m/s

Explanation:

Let us assume that in a plane mirror if the mirror moves at speed of v, then the image that appears on the plane mirror moves at speed of 2v. That is in the case of mirror is moving with the speed of v= 10m/s-1... hence the option b is correct .

s= 20ms -1 is the correct answer..
