Question

an object is placed at a distance to f from the pole of a convex mirror of focal length small f the linear magnification is​

Answer 1

Answer:

Here,

Object distance, u=−2f

Image distance, v=?

From mirror formula, 

v1+u1=f1

v1+−2f1=f1

v1=2f3

v=32f

Now,

Magnification, M=u−v

=−(−2f)32f

=31

(M is positive for convex mirror
