In the given figure, the object is placed at the centre of curvature of the mirror. Find the instantaneous velocity of image at the shown instant (in cm/s)

Text Solution

Verified by Experts

The correct Answer is:
5
`vecV_(im)=-(v^(2))/(u^(2))vecv_(om)`
`0-(40)/(13)=-((-10)/(-10+x))^(2)(10-(40)/(13))`
`(-10)/(-10+x)=+-(2)/(3)`
`x=25,-5cm`
Object is infront of mirror
Hence `25cm`
