Explanation:
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.Read more on Sarthaks.com - https://www.sarthaks.com/22947/a-concave-mirror-of-focal-length-10cm-is-placed-at-a-distance-of-35cm-from-a-wall
