Question

vector form of coloumbs low​

Answer 1

r. 21| , and ε0 is the electric constant. The vector form of Coulomb's law is simply the scalar definition of the law with the direction given by the unit vector, r̂21, parallel with the line from charge q2 to charge q1.

Answer 2

vector F12 =-F21vector

the forces exerted by two point charges on each other are equal in magnitude and opposite in direction .
