Label the forces acting on the sphere in the diagram of a charged sphere suspended in an electric field.

1: Tension (T), 2: Gravitational force (mg), 3: Electric force (Fₑ)

What are the steps of charging by friction?

Rubbing objects together transfers electrons, creating charged objects.

What are the steps of charging by conduction?

Direct contact allows electrons to flow, equalizing charges.

What are the steps of charging by induction?

Bringing a charged object near a neutral one redistributes charges within the neutral object.

How do you apply Coulomb's Law?

Identify the charges (q1, q2), measure the distance (r) between them, and use the formula: $F = k * \frac{|q1 * q2|}{r^2}$

What are the differences between Gravitational Force and Electromagnetic Force?

Gravitational Force: Always attractive, weaker at short distances, acts on all matter | Electromagnetic Force: Attractive or repulsive, stronger at short distances, acts only on charged particles

What is the difference between Scalar and Vector Fields?

Scalar Field: Assigns a single value (e.g., temperature) | Vector Field: Assigns a vector (e.g., velocity, force)
