A glass rod that has been charged to +12.0 nC touches a metal sphere. Afterward, the rod’s chargeis +8.0 nC. In both cases the fractional uncertainty is 1%. a. What kind of charged particle was transferred between the rod and the sphere, and in whichdirection? That is, did it move from the rod to the sphere or from the sphere to the rod? b. How many charged particles were transferred?   Give full explanations

In Configuration 1 below, what is the magnitude of the predicted electric field at point b? Point b is 2.00 m from the +3.00 nC charge (this is also in your lab procedure). Pt. a Pt. b Pt. c +3 nC figure 1 a Your answer should: Be in the Correct SI Units of N/C Be rounded to 2 Decimal Places For this problem you can't enter a number in Scientific Notation (the program doesn't allow it). For example: 2.06 x 102 would be written as 206.00
