										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.
So
F=\frac{kq_{1}q_{2}}{r^{2}}
putting all the values
F= 2.304\times 10^{-24} N
Thanks and Regards

										The charge q1 & q2 are placed at corner of square find q2 such that the resultant force on q1 is zero
