LAW:-
The force of attraction or repulsion b/w 2 point charges is directly proportional to the product of the magnitude of charges and inversely proportional to the square of the distance b/w them.
Mathematicaly:-
F proportional q1q2 -eq (1)
F proportional 1/r^2 -eq (2)
Combining eq 1 and 2 we get
F=k q1q2/r^2
F proportional q1q2 -eq (1)
F proportional 1/r^2 -eq (2)
Combining eq 1 and 2 we get
F=k q1q2/r^2
Here f is force q1 and q2 are charges and r is the distance taken in square.k is coulombs constant.
K:- The SI unit value of k is 9×10^9 Nm^2c^-2
K:- The SI unit value of k is 9×10^9 Nm^2c^-2
