Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Electric Charges and Coulomb's Law Coulomb’s Law
Coulomb's law in vector form is given by-
1
\({F} = \frac{kq_1 q_2}{r^2}\)
2
\({F} = \frac{kq_1 q_2}{\vec{r^2}}\)
3
\(\vec{F} = \frac{kq_1 q_2}{r_{21}^2}\hat r_{21}\)
4
\({\vec F} = \frac{kq_1 q_2}{\vec{r^2}}\)
