To Explain: The answers for the object distance are not the same.
Answer to Problem 78GP
The object distance has two values:
Explanation of Solution
Given info:
Radius of curvature of the concave mirror,
Formula used:
Mirror formula is given by:
Here,
Calculation:
Firstly, the focal length can be calculated from the given data as follows:
Now, according to the given statement, the magnification can be written as:
So, the object distance can be calculated as:
Hence, the image distance can be given as:
Hence, the students don’t need to repeat the lab.
Conclusion:
Thus, the object distance has two values:
