Any object carrying a charge will experience a force when in the presence of another body also carrying a charge
This force is given by Coulomb's Law
The formula is:
The value of the constant is 8.99 x 10^9
Coulomb's law follows the inverse square law

Difference betwwen electrical field strength and e
Electric Field Strength is defined as the force per unit charge experienced by a test charge at that point
The Electric Potential at a point in an electric field is defined as the work done in bringing a test unit positive charge from infinity to that point.
The potential charge at infinity is always defined to be zero.
Electric Field Strength is a vector quanitity and Electric Potential is a scalar quantity.

Equipotentials
In an electric field, you have areas were the electrical potential are the same
These areas can be connected by lines called equipotentials
The closer these lines are, the stronger the field. The further the lines the weaker the field.

Difference Between Radical and Uniform feilds
Uniform Fields have the same electical field strength.
Radical Fields have different electical field strenths.
