2. There were many combinations that showed if it was positive or negative charges. The positive combinations were the glass and fur (3.108 nC), clear plastic and fur (45.07 nC), glass and silk (1.979 nC), clear plastic and silk (19.60 nC), glass and green cloth (2.914 nC), clear plastic and green cloth (31.09 nC) materials. The negative combinations were the yellow plastic and fur (-81.57 nC), yellow plastic and silk (-75.49 nC), and yellow plastic and green cloth (90.30 nC) materials. The results are positive when the electrons flow from the glass and clear plastic because these materials have more electrons than the other materials, thus the electrons would flow from high concentration to low concentration. When the combinations are negative, that means that the electrons would flow into
