the force of attraction or repulsion = (k*q1*q2*r')/r^3
where r' is the position vector
Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector. For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.
explain the vector representation of Coulom's law.
Yes.
NO
Yes subtraction of vector obeys commutative law because in subtraction of vector we apply head to tail rule
ya they just accidentally said law of vectors instead.
The parallelogram law of vector addition states that if two vectors are represented as two adjacent sides of a parallelogram, the resultant vector can be obtained by drawing a diagonal from the point where the two vectors originate. Mathematically, this law can be expressed as ( R^2 = A^2 + B^2 + 2AB \cos(\theta) ), where ( R ) is the magnitude of the resultant vector, ( A ) and ( B ) are the magnitudes of the two vectors, and ( \theta ) is the angle between them. This law illustrates how vectors can be combined geometrically and is fundamental in understanding vector addition in physics and mathematics.

Maxwell's equations contain two scalar equations and two vector equations. Gauss' law and Gauss' law for magnetism are the scalar equations. The Maxwell-Faraday equation and Ampere's circuital law are the vector equations.
If three vectors form a triangle , their vector sum is zero.
Using Gravesand's apparatus
no because triangle only contain three vectors and if many vector are added then they cant form a triangle
