A thief is running away in a car with velocity of 20 m/s . A police jeep is following him, which is sighted by thief in his rear view mirror which is a convex which is a convex mirror of focal length 10 m . He observes that the image of jeep is moving towards him with velocity of 1 cm/s . if the magnification of the mirror for the jeep at that time is 1/10 . find (a) actual speed of jeep (b) rate at which magnification is changing . Assume that police jeep is on axis of the mirror.
