Which statement is true about the induction of static charges?

The statement that induction of static charges does not require contact between objects is accurate because induction refers to the process of inducing a charge in an object without actual physical contact. Instead, when a charged object is brought near a neutral conductor, it causes the distribution of charges within that conductor to rearrange. This happens because the electric field of the charged object influences the electrons in the neutral object, resulting in one side becoming positively charged and the other side negatively charged, creating an induced charge.

This phenomenon is fundamental in understanding how static electricity can build up and affect electrical systems and devices without direct interaction. It illustrates important principles of electrostatics, particularly in fields like electronics and electrical safety. The other statements do not align with the principles of static charge induction; they either incorrectly imply direct contact, limit the process to liquids, or dismiss its relation to electricity altogether.
