What are the units of charge?
admin The concept of unit charge can be cleared easily from equation 1.3. Lets suppose r=1m, q1=q2=q and the force F=9 X 10 9. By substititing the values in equation 3…
What is dielectric constant or electrical permittivity?
When the charges are located in some other medium rather than vaccum then the force between the charges will be : ————— 1.4 Where is the absolute electric permittivity of…
What is the relation of forces between charges according to the position vectors
Suppose two point charges q2 and q1 are located in space at different positions A and B . O is the origin of rectangular co-ordinate system XYZ. This is shown…
What is Superposition Principle ?
By using this principle we can calculate total amount of force on a given charge due to a number of point charges. According to this principle the total amount of…
What is continuous charge distribution?
As we all know that the charge is always quantized. Pertaining to the smallest amount of charge is that it can exist as +e or –e. It is the charge…
What is electrostatic field?
When a charge q is placed near to any other charge q1 then it feels some force of attraction or repulsion. Hence we can say that the force experienced by…
What is the relation between Electric field intensity and force?
The strength of electric field at a particular point is called as Electric Field intensity. In other words, the force felt by a unit positive charge situated at a point…
What will be the electric field intensity due to a point charge?
Let’s think that we want to calculate the electric field intensity at point p caused by charge q at some point O. So, OP=r. Lets suppose a test charge having…
What are Electric Lines of Force?
The invention of electric lines of force was done by famous scientist Michael Faraday. These do not provide the full info about electric field, but provide us with quantitative partial…
What will be the electric field intensity due to a group of charges?
At any point electric field intensity is the total sum of all the electric field intensities generated due to different charges at the same point. If other charges are absent…
