Law of electrostatics |
Like charges repel one another and unlike charges attract one another |
|
|
Conductors and Insulators |
Electric conductors are materials in which electric charges move freely, whereas electric insulators are materials in which electric charges cannot move freely |
|
|
Coulomb Law |
Coulomb Law states that the electric force between two point charges is proportional to the product of charges and inversely proportional to the square of the distance between them. |
|
|
Electric field strength |
The electric field strength at a point in an electric field is defined as the force per unit charge on a positive charge at that point. |
|
|
Electric field |
It is a region of space in which any charged body placed there will experience an electrostatic force. |
|
|
Electric Potential V |
The electric Potential V at a point in an electric field is defined as the work done per unit charge in bringing a small test charge from infinity to that point. |
|
|
Equipotential Surface |
All points in a field which which have the same potential can be imagined as lying on a surface called an equipotential surface. |
|
|
The electric potential U |
The electric Potential U of a charge in an electric field is defined as the work done in bringing the charge from infinity to that point. |
|
|
Oil drop experiment |
qE = qV/d = mg |
|
|
Motion of charged particle moving parallel to the electric field |
Force and acceleration constant Work done = Fd = Eqd = Vq Gain in KE = Vq |
|
|
Motion of charged particle with initial velocity perpendicular to electric field |
Parabolic Path |
