A proton is placed in a uniform electric field of $2.75 \times 10^{3} \mathrm{~N} / \mathrm{C} .$ Calculate (a) the magnitude of the electric force felt by the proton; (b) the proton's acceleration; (c) the proton's speed after $1.00 \mu \mathrm{s}$ in the field, assuming it starts from rest.

Key Concepts

Newton's Second Law

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, formulated as F = ma. This law is crucial for determining the acceleration of charged particles once the electric force acting upon them is known.

Electric Field

An electric field is a region in space where a charged particle experiences a force. It is defined as the force per unit charge and is characterized by both magnitude and direction. In a uniform electric field, the field strength remains constant in magnitude and direction throughout the region.

Electric Force on a Charged Particle

When a charged particle is placed in an electric field, it experiences a force that is directly proportional to the magnitude of its charge and the electric field strength. This relationship is expressed mathematically by F = qE, where F is the force, q is the charge, and E is the electric field. This concept is fundamental in understanding how charges interact with electric fields.

Constant Acceleration Kinematics

In situations where an object experiences constant acceleration, such as a charged particle in a uniform electric field, kinematic equations can be applied to determine various aspects of the object's motion. These equations relate displacement, initial velocity, time, acceleration, and final velocity, and are essential for predicting how the motion evolves over time.
