1

A charged object has...

imbalance in positive and negative charges.

2

Static electricity is created by...

friction, the electrons are transferred from one object to another.

3

Electric charge is a feature of...

certain elementary particles, that causes them to interact with each other.

4

Unit of charge is...

coulomb (C)

5

One C is equivalent...

to the charge transported by 1 ampere of current in 1 second.

6

An electric field is...

a region where a charged particle will experience a force.

7

Electric field lines represent:

-the direction of the field(direction in which a positive particle would move)
-the space between lines represents the strength

8

Two parallel plates=

uniform electric filed

9

In the uniform field the force...

is everywhere the same.

10

In radial uniform filed the force...

is not the same everywhere.

11

The electric field strength at a point...

is the force experienced per unit charge exerted on a stationary positive charge at that

12

Electric field strength =

F/charge (NC-1) or p.d./separation (Vm-1)

13

Acceleration of particle=

F x electric fore / mass
