Question

Name: (10 points) The figure below displays three poin distances from each other. t charges of varying strengths and 6. +12 nC.<-4.00 m -p Below are a number of changes in this situation that are described as options (a) through (d). For each change, you are to identify how the change will impact, if it will, the electric potential at the Point P. 3.00 m 5.00 m 3.00 m 4.00 mO +9 nC The following choices for possible effects apply to all described changes. They are: (a) This change will increase the electric potential at pointP (b) This change will decrease the electric potential at point P. (c) This change will not affect the electric potential at P (d) The effect of this change cannot be determined with given information. If you choose (d), please explain below. +15 nC 1) One of the charges is removed 2) The magnitude of one of the charges is increased. 3) The sign of one of the charges is reversed. 4) The sign of one of the charges is reversed and its magnitude doubled 5) The magnitude of one of the charges is doubled while another is removed 6) The distance between two of the charges is decreased. 7) The signs of all three charges are reversed

Answer 1

1)since all the charges are positive, removing one of the charges will rdecrease potential at P

2)increasing magnitude of one of the charges will increase the potential at P

3)if sign of one of the charge is reversed, the potential at P will decrease since one of the charges wilp become negative

4)potential at A will reduce
