A explicação para o fato de uma haste de metal segurada na mão e esfregada com uma pele não se tornar carregada é porque as cargas podem se mover livremente entre o metal e o corpo humano. Portanto, a alternativa correta é: "A metal rod held in the hand and rubbed with a skin does not become charged because the charges can move freely between the metal and the human body."
