Question

show coloumb law in vector form

Answer 1

coulomb law in vector form is
$\\ F_{q_{2} \: q_{1}} =(k \frac{q_{1} q_{2} }{ {r}^{2} } ) \bold{ \hat{r}}$
F is the force, and $\bold{ \hat{r}} \:$ represents the line of force joining from q1 to q2

Answer 2

Force is a vector quantity as it has both magnitude and direction. The Coulomb's law can be re-written in the form of vectors. Remember we denote the vector “F” as F, vector r as r and so on. Let there be two charges q1 and q2, with position vectors r1 and r2 respectively.
