Was the movement of charges experienced in the lab more from the sticky side of the tape, or the plastic outer surface of the tape? OCharges were transferred using the sticky side Charges were transferred due to the plastic material of the tape. Both were equally involved The transfer was due to another mechanism

Three pairs of identical, conducting spheres are initially charged as shown: 6e -6e 0 -8e 7e Each pair is brought into contact and then separated. Determine e (a) the final or residual charge on each sphere in the pair, and (b) the charge transferred in each pair during contact. Show transcribed image text

Two small spheres spaced 20 cm apart have equal charge. How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 4.57 x 10-21 N Show detailed solution
