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:
a. 2.26×10−3 m/s away from the lens
b. 0.92×10−3 m/s away from the lens
c. 3.22×10−3 m/s towards the lens
d. 1.16×10−3 m/s towards the lens
