Compute all part of following problem given below:
Problem: A 30 µF capacitor has a layer of salt (dielectric constant of 5.9) between the plates. It is charged by a 9 V battery. While remaining on the battery, the salt is removed.
Part A: What is the new capacitance?
Part B: What is the new voltage?
Part C: What is the new charge?
I need tutor help to solve the above problem and give a numerical answer for each part of above problem.
