Question

In order to obtain magnification of _1.5 with a concave mirror of focal lenght 16cm the object will have to be placed at a distance

Answer 1

HEY MATE!

magnification = f/( f+u)

-1.5 = 16/16+u

-1.5 (16+u)=16

16+u=16/-1.5

u=-10.2-16

u=-26.2cm

where negative sign indicates the position.
