Q: A charged particle moves in a uniform electric field. What is the nature of the force acting on it?
Solution: In a uniform electric field, the force acting on a charged particle is constant in magnitude and direction.
Steps: 5
Step 1: Understand what a charged particle is. A charged particle is an object that has an electric charge, which can be positive or negative.
Step 2: Know what a uniform electric field is. A uniform electric field is a region where the electric field strength is the same at every point.
Step 3: Recall the formula for the force on a charged particle in an electric field. The force (F) is calculated using the formula F = qE, where q is the charge of the particle and E is the electric field strength.
Step 4: Recognize that in a uniform electric field, both the charge (q) and the electric field strength (E) are constant.
Step 5: Conclude that since both q and E are constant, the force (F) acting on the charged particle is also constant in both magnitude (size) and direction.
