Final answer:
The image formed by the concave mirror is virtual and located at a distance of -17.06 cm from the mirror.
The size of the image is 2.41 times the size of the object.
Step-by-step explanation:
To find the location and size of the image formed by the concave mirror, we can use the mirror equation.
The mirror equation is given by: 1/f = 1/do + 1/di, where f is the focal length of the mirror, do is the object distance, and di is the image distance.
Given that the radius of curvature (R) is twice the focal length (f), we can calculate f = R/2 = 10.20/2 = 5.10 cm. Substituting the given values into the mirror equation and solving for di, we get di = -17.06 cm.
The negative sign indicates that the image is formed on the same side as the object, which means it is a virtual image.
The magnification, m, can be calculated using the formula: m = -di/do. Substituting the values, we get m = -17.06/7.10 = -2.41. The negative sign indicates that the image is inverted compared to the object. The absolute value of the magnification, |m|, represents the size of the image compared to the object.
Therefore, the size of the image is 2.41 times the size of the object.
