Final answer:
Charging an object by polarization does not require direct contact with a charged object but instead involves inducing a charge separation by proximity.
Step-by-step explanation:
The statement that charging an object by polarization requires touching it with an object carrying excess charge is false. Charging by polarization occurs when an electrically charged object is brought near another object without touching it, inducing a separation of charges within the object. There is a shift of electrons within the object, which results in one side of the object becoming more positively charged and the other side more negatively charged, without a net transfer of charge to the object.
