Final answer:
To find the image position in front of a concave mirror, we use the mirror equation. With the object at 60 cm and the focal length at 20 cm, the image is located 30 cm in front of the mirror, which is a real image.
Step-by-step explanation:
The question asks for the image position when an object is placed in front of a concave mirror. To solve this, we can use the mirror equation: 1/f = 1/do + 1/di, where 'f' is the focal length, 'do' is the distance of the object from the mirror, and 'di' is the distance of the image from the mirror. Given that the focal length is '20 cm' and the object distance 'do' is '60 cm', we substitute these values into the mirror equation.
1/20 = 1/60 + 1/di => 1/di = 1/20 - 1/60 => 1/di = (3 - 1)/60 => 1/di = 2/60 => di = 30 cm
Since the value is positive, it indicates that the image is formed on the same side of the mirror as the object, which means it's a real image. Therefore, the correct answer is B) 30 cm in front of the mirror.
