Solve the following problem given below:
Problem: A 107-mm-focal-length lens is used to focus an image on the sensor of a camera. The maximum distance allowed between the lens and the sensor plane is 135mm.
Part I: How far in front of the sensor should the lens (assumed thin) be if the object to be photographed is 10.0 m away from the lens? Follow the sign conventions.
I need help to solve the above question and express your answer to three significant figures and include the appropriate units.
