1
Q

What is an electric field, general description?

A

This field is a conceptual quantity exists in all space

2
Q

What is the electric field(E)?

A

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

3
Q

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

A

E = F / Q (V/m)

4
Q

How can a force acting on a charge be calculated?

A

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

F = EQ

5
Q

The E field of a positive point charge?

A
6
Q

Superposition of electric fields(like charges)?

A
7
Q

Electric field structure (like Charges)

A
8
Q

Superposition of electric fields(unlike charges)

A
9
Q

How can the acceleration of a charged particle be calculated?

A

F = ma & F = Eq

a = qE/m

SUVAT can then be used to solve problems

V = u + at
