If an observer is walking away from the plane mirror with 6 m/s. Then the velocity of image with respect to observer will be –
A
6 m/s
B
– 6 m/s
C
12 m/s
D
3 m/s
Answer
12 m/s
Explanation
Solution
= 
m/s, 
= 
– 
,= –6
m/s
Velocity of image w.r.t. observer = 
= 
– = –
– 
= –12
= 12 m/s away from mirror
