Question

Ram moves away from a plane mirror with a speed of 5m/s, find the distance between Ram and his image after 25 seconds:

Answer 1

Dear Student,

◆ Answer -

Distance between Ram and his image = 250 m

● Explanation -

Distance between Ram and mirror after 25 s is 5×25 = 125 m.

For plane mirror, image distance is equal to object distance. So distance between Ram and his image is 2×125 = 250 m.

Thanks dear for asking. Hope this is helpful to you...

Answer 2

The distance between Ram and his image is $2\times 125=250\ m$.

Explanation:

Given that,

Ram moves away from a plane mirror with a speed of, v = 5 m/s

The distance between the object and the mirror in  25 seconds is :

$d=u\times t$

$d=5\ m/s\times 25\ s$

d = 125 s

We need to find the distance between Ram and his image after 25 seconds. As we know that the object distance and image distance both are same for a plane mirror. So,

The distance between Ram and his image is $2\times 125=250\ m$.
