Final Answer:
The observed charging of the wall when the negatively charged balloon is brought near it is likely due to electrostatic induction. Induction is a process by which charges in a neutral object become separated in the presence of a charged object, without direct contact. In this scenario, the negatively charged balloon induces a redistribution of charges on the wall's surface. The answer is option 1) Due to induction
Step-by-step explanation:
The apparent charging of the wall when a negatively charged balloon is brought near it suggests a phenomenon known as electrostatic induction. Initially, the wall might have had an equal number of positive and negative charges, resulting in a neutral state. When the negatively charged balloon is brought close, it repels electrons within the wall, causing a temporary separation of charges.
Electrons in the wall are repelled, leaving behind a region with a deficit of electrons, making it positively charged. Simultaneously, the electrons on the side of the wall closer to the balloon are attracted, causing an accumulation of electrons and resulting in a negative charge. This induced charge separation occurs without direct contact between the balloon and the wall.
This phenomenon demonstrates the transfer and redistribution of charges through electric fields, showcasing how objects can become charged through proximity and influence from charged objects without direct contact.
