Write the vector form of force between two charges `q_1 and q_2` having ` r_1 and r_2` as their position vectors, respectively .

Force between two charges q_1 and q_2 separated by a distance r is proportional to q_1q_2//r^(2). Proportionality constant is

Force between two charges separated by a distance r varies as r^(2) ?

The force acting between two point charges q_(1) and q_(2) kept at some distance apart in air is attractive or repulsive, if (i) q_(1)q_(2) gt 0" " (ii) q_(1)q_(2) lt 0

The electrostatic force between two charges Q_(1) and Q_(1) separated by a distance r is given by F="k"(Q_(1)Q_(2))/(r^(2)) . The constant k depends on
