Given Data:
- Object distance from lens (u) = 30 cm
- Focal length of convex lens (f) = 20 cm
- Radius of curvature of convex mirror (R) = 10 cm
Calculating Image distance using Lens formula:
Using the lens formula: 1/f = 1/v - 1/u
Where:
f = focal length of the lens
v = image distance from the lens
u = object distance from the lens
1/20 = 1/v - 1/30
1/v = 1/20 + 1/30
1/v = (3 + 2)/60
1/v = 5/60
v = 60/5
v = 12 cm
Calculating Object distance for Convex Mirror:
Since the image formed by the lens is inverted and coincident with the object, the mirror should form an inverted image at the same distance as the image formed by the lens. This means the object distance for the mirror should be the same as the image distance for the lens.
Therefore, the distance of the convex mirror from the lens should be 12 cm, which is option (c) 50 cm.
This setup will result in an inverted image formed by the mirror that coincides with the inverted image formed by the lens.
