Step 1: Number of atoms in 1 kg of dry human hair, N = 4 × 10^20. Step 2: Charge of one electron, e = 1.6 × 10^-19 \, C. Step 3: Total charge released, Q = N × e. Substitute the values: Q = (4 × 10^20) × (1.6 × 10^-19) \, C Multiply the coefficients and add the powers of 10: Q = (4 × 1.6) × 10^20 + (-19) \, C = 6.4 × 10^1 \, C Simplify: Q = 64 \, C The correct option is (b). 64 C
