Questions & Answers

Q: What is the definition of an electric field?

The electric field is the force per unit charge at a given point, describing the force a charge would experience when placed in that field.

Q: How is the direction of an electric field determined?

The direction of an electric field around a charge is based on the positive test charge; towards a negative charge and away from a positive charge.

Q: How is the magnitude of an electric field calculated?

The magnitude of an electric field at a distance from a charge is calculated using the equation E = kQ/r², where k is Coulomb's constant, Q is the charge, and r is the distance.

Q: How can the acceleration of a particle in an electric field be determined?

The acceleration of a particle in an electric field is calculated by multiplying the charge of the particle by the electric field strength and dividing by the mass of the particle.
