During an electrostatic demonstration, a teacher rubs a glass rod with a silk cloth. The glass rod acquires a net positive charge of +8.0 × 10-11 C.
Taking the elementary charge to be e=1.6×10−19 Ce = 1.6 \times 10^{-19}\text{ C}e=1.6×10−19 C, which statement correctly explains this observation in terms of particle transfer?
5.0×1085.0 \times 10^85.0×108 protons have been transferred from the silk cloth to the glass rod.
5.0×1085.0 \times 10^85.0×108 electrons have been transferred from the glass rod to the silk cloth.
5.0×1085.0 \times 10^85.0×108 electrons have been transferred from the silk cloth to the glass rod.
5.0×1085.0 \times 10^85.0×108 protons have been transferred from the glass rod to the silk cloth.
