Question

3) object is at centre of curvature​

Answer 1

$\huge\tt\red{Answer}$

.Image of an object placed at center of curvature is inverted, real and of the same size and is formed at the center of curvature. Hence image will be real and at the center of curvature (20 cm from mirror).

Answer 2

Answer:

Hey What's Here is your answer mate....

Image of an object place an centre of curvature is inverted, real and of the same size and is formed at the centre of curvature.

Hence image will be real and at the centre of curvature.

The centre of curvature of curve is found at the point that is at the distance from the curve equal to the curvature lying on the normal vector.

It is the point that infinity if the curvature is zero.

The osculating circle of the curve is centered at the centre of curvature.

I hope it will help you....
