Question 2 1 pts Derive the error equation for Q = Emiarz 2k using the calculus method described in the Phys 156 Laboratory Resources videos, slides or lab guidebook. Write down the equation and have an instructor check it before you use it in step 6 of the sample calculation for the value of the point charge in the simulation. You do not need to show or submit the derivation steps.
