The principle of charge conservation is used to answer the given question.

After a point charge, +7Q, is placed inside the cavity of a conductor, electrostatic equilibrium is attained. After an additional charge of amount, -5Q, is placed on the surface of the inner cavity. electrostatic equilibrium is attained once again. What is the net charge on the inner and outer surfaces of the conductor, respectively?

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

**Explanation of the Diagram:**

The diagram illustrates a conductor with a cavity inside it. Within this cavity, a charge of +7Q is placed. The surrounding material is labeled as "Conducting Material," and the space inside is labeled as "Cavity."

**Description of the Problem:**

A point charge, +7Q, is initially placed inside the cavity of a conductor, achieving electrostatic equilibrium. Subsequently, an additional charge of -5Q is placed on the surface of the inner cavity, leading to a new state of electrostatic equilibrium. The question asks for the net charge on the inner and outer surfaces of the conductor, respectively.

**Answer Choices:**

a. -2Q, -7Q
b. -7Q, -2Q
c. +7Q, +2Q
d. -7Q, +2Q
e. +7Q, -2Q

**Objective:**

Determine the correct net charges on the inner and outer surfaces of the conductor after equilibrium is reached with the additional charge.
