Final answer:
The image formed by a concave mirror placed 0.15m in front of it has a position of 0.2m, is real in nature, and has a magnification of -1.5.
Step-by-step explanation:
The image formed by a concave mirror can be found using the mirror formula:
1/f = 1/v - 1/u
Where f is the focal length of the mirror, v is the image distance, and u is the object distance.
Plugging in the given values:
1/0.1 = 1/v - 1/0.15
Solving this equation, we find that v = 0.2m.
The nature of the image can be determined by the sign of v. Since v is positive, the image is real.
The magnification can be found using the formula:
m = -v/u
Plugging in the values, m = -0.2/0.15 = -1.33. So, the correct option is:
Position: 0.2m, Nature: Real, Magnification: -1.5 (option a).
