Two objects And B when placed in front of a concave mirror give image ...


Given Information:
- Focal length of concave mirror (f) = 7.5 cm
- Size of object A (hA) = 3hB
- Distance of object A (uA) = 30 cm
- Image size of objects A and B are equal

Calculating Image Size:
- Since the image sizes of objects A and B are equal, we can use the magnification formula:
Magnification (m) = -v/u = h'/h = -f/(u-f)
- For object A:
m = -f/(uA-f) = hA/hA = 1
-7.5/(30-7.5) = 3
-7.5/22.5 = 3
-1/3 = 3
- For object B:
m = -f/(uB-f)
-7.5/(uB-7.5) = 1
-7.5 = uB - 7.5
uB = 0 cm

Conclusion:
- The distance of object B from the mirror is 0 cm when object A is placed 30 cm from the mirror.
