Answer 1

Answer:

Image result for A concave mirror of focal length 10cm placed at distance of 35cm from a wall. How far from the wall an object be placed so that it’s image formed by the mirror falls on the wall

Here, f =-10cm; v =-35 cm (since the image is formed on the wall and distance between the wall and mirror is 35cm). Image is beyond 2f so object has to be in between F and C. Let the distance of the object from the wall be x. Therefore, the distance of the object from the wall = 21 cm.
