Coulombs Law

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
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
