Sol. Minimum charge of a body is the charge of an electron Wo, q = 1.6 × 10^–19 c x = 1 cm = 1 × 10^–2 cm So, F = kq base 1q base 2/r^2 = 9 * 10^9 * 1.6 * 1.6 * 10^-19/10^-2 * 10^-2 = 23.04 * 10^-38+9+2+2 = 23.04 * 10^-25 = 2.3 * 10^-24

the distance is constant so force depends only on charge. so the force is minimum when charge is minimum i.e. charge of one electron.

$F=\frac{kq_{1}q_{2}}{r^{2}}$

putting all the values

F= $2.304\times 10^{-24} N$

F on q= vector of (F1+F2+F3)

0=F1+F2+F3(vector)

=kqQ/a^2(i+j)+kq^2/root2a^2 i+j/root2

0=kqQ/a^2+kqQ/2root2a^2

qQ+q^2/2root2=0. q= -2root2Q
