1.
Can two equipotential surfaces with different potential values ever intersect or
cross?
Answer and explain briefly.
No they cannot ever intersect or cross because they are relative to the distance away from
the individual charges and therefore it is impossible for them to ever intersect.
2.
Do the numerical values of equipotentials get larger or smaller the closer the
equipotentials are to a negative charge?
Answer and explain briefly.
The values get larger, and that is because the closer it gets to the charge, the value of r
gets smaller and smaller, and when you divide by r, it increases the value of the
equipotentials
3.
Write each of the four leastsquares results for the resistance (slope)
measurements, including the uncertainties, in standard form.
Also, write down
the average ± standard deviation obtained from Excel in standard form.
