An object 3cm hight is placed at it distance of 10cm in fornt of convcaving mirror of focal length 20 cm .Find the position natural and size of the image format

Answer»

O=3cm
u=(-10)cm
Since,
it is a concave mirror.
Therefore,
f=(-20)cm

\frac{1}{f}  =  \frac{1}{v} +  \frac{1}{u} \\  \frac{ - 1}{20} =  \frac{1}{v} +  \frac{ - 1}{10} \\ after \: solving \: this \: \\ v = 20cm.
I/O = v/u
I/(-10)=20/(-10)
I=20cm.
