Answer 2

The angular position from mirror A at which image is not formed is (3) 115°

The object is at an angular distance of 20° from the mirror A.

As it is a plain mirror, the image will form at a same distance from the mirror at which distance the object is placed from it.

So, the primary image will be at an angular position of 20° from mirror A.

Here, two plain mirrors, A and B are used.

So, there will be more than one image and the images will be at a form of circle.

So, the other images will be at some angular positions from mirror A, they can be:

(90 - 20) = 70°

(90 + 20) = 110°

But it can not be 115°.
