An object is moving with velocity

0.01 \text{ m/s}

towards a convex lens of focal length

0.3 \text{ m}

. Find the magnitude of rate of separation of image from the lens when the object is at a distance of

0.4 \text{ m}

from the lens. Also calculate the magnitude of the rate of change of the lateral magnification.
