Question

An object in place at a distance of 20m from a convex mirror of focal length 30m then find the size and nature of image​

Answer 1

Explanation:

From lens equation

v1−u1=f1

v1−(−20)1=(.3)1=310

v1=310−201

v1=60197;v=19760

Velocity of image wrt. to lens is given by vI/L=m2vO/L

direction of velocity of image is same as that

of object

vO/L=5m/s

vI/L=(197×2060×1)2(5)

1.16×10−3m/s towards the lens
