An object is at a distance of 20 m from a convex lens of focal length 0.3 m. The lens forms an image of the object. If the object moves away from the lens at a speed of 5 m/s, the speed and direction of the image will be :

1. 1.16 × 10 –3 m/s towards the lens
2. 2.26 × 10 –3 m/s away from the lens
3. 3.22 × 10 –3 m/s towards the lens
4. 0.92 × 10 –3 m/s away from the lens

Correct answer: 1.16 × 10 –3 m/s towards the lens
