During electrification by friction, 20 · 10 ^ 20 electrons are transferred from body A to body B. What charge does body B have?
These problems: n (the number of electrons transferred to body B after electrification by friction) = 20 * 10 ^ 20 electrons.
Constants: qe (electron charge) = -1.6 * 10 ^ -19 C.
To determine the charge of the body B, we apply the formula: q = n * qe.
Let’s calculate: q = 20 * 10 ^ 20 * (-1.6 * 10 ^ -19) = -320 Cl.
Answer: After electrification by friction, body B will have a charge of -320 C.
