How is a charged object able to move other objects from a distance?

• A. By transferring electrons directly through physical contact
• B. By creating an electric field that exerts a force on other charges according to $F=qE$
• C. By increasing its mass to attract other objects gravitationally
• D. By emitting magnetic waves that push other objects away

Answer: (B)

Verified step by step guidance

1. Understand that a charged object influences other objects without needing to touch them by creating an electric field around itself.
2. Recall the fundamental relationship between force, charge, and electric field, given by the equation \(F = qE\), where \(F\) is the force experienced by a charge \(q\) in an electric field \(E\).
3. Recognize that this electric field extends through space and can exert forces on other charged objects at a distance, causing them to move.
4. Note that this interaction does not require physical contact or transfer of electrons; instead, it is the presence of the electric field that causes the force.
5. Understand that other options like increasing mass for gravitational attraction or emitting magnetic waves are not the primary mechanisms for a charged object moving others from a distance in this context.
