DESCRIBE ALL ABOUTTOPIC-(COULOMB'S LAW IN VECTOR ADDITION)........DESCRIBE IT IN EASY WAY....
The Coulomb’s law in vector addition follows the commutative law and the associative law of vector addition.
If there are three charges at A, B and C. Suppose the force on charge at A due to the charge at B is FB and the force due to the charge at C is FC. If the net force on the charge at A is F then,
F = FB + FC = FC + FB
This is the commutative law.
Suppose, we need the net electric field at a point P due to the three charges. EA, EB, EC are the electric fields at P due to the charges. So, the net field at P is,
E = EA + EB + EC = (EA + EB) + EC = EA + (EB + EC)
If a charge ‘q’ is placed at P the force experienced by the charge is,
qE = qEA + qEB +q EC = (qEA + qEB) + qEC = qEA + (qEB + qEC)
=> F = FA + FB + FC = (FA + FB) +FC = FA + (FB + FC)
This is the associative law.
