Topic 2: Electric Fields

Question 1

What is an electric field, general description?

Answer 1

This field is a conceptual quantity exists in all space

Question 2

What is the electric field(E)?

Answer 2

The E field at a point in space is the force acting on a unit positive charge placed at that point.

Question 3

The equation for E field strength on a test charge at a point in space?

Answer 3

E = F / Q (V/m)

Question 4

How can a force acting on a charge be calculated?

Answer 4

The force acting on a charge can be calculated from the E in which it is placed.

F = EQ

Question 5

The E field of a positive point charge?

Answer 5

Question 6

Superposition of electric fields(like charges)?

Answer 6

Question 7

Electric field structure (like Charges)

Answer 7

Question 8

Superposition of electric fields(unlike charges)

Answer 8

Question 9

How can the acceleration of a charged particle be calculated?

Answer 9

F = ma & F = Eq

a = qE/m

SUVAT can then be used to solve problems

V = u + at
