Coulomb's Law of Electrostatic Force:
It states that ‘Any two point charges exert force on each
other and this force is directly proportional to product of their charges and
inversely proportional to distance between them.’
In the above diagram two charges are placed r meters away from each other with
magnitudes of their charges q1
and q2.
Mathematically,
Where K is the constant of proportionality, and its values
depends upon the medium placed between two charges.
When both charges are positive or both positive, they will
repel each other with the force described above. When one charge is positive
and other negative they will attract each other will the force given in the
above equation.
The value of K
for free space is 8.98755 × 109 Nm2/C2.
What does free space mean?
ReplyDeleteSimple free space means where no medium is placed between two charges
