Two positively charged small particles, each of mass `1.7 xx 10^(-27) kg` and carrying a charge of `1.6 xx 10^(-19) C` are placed apart at a separation r. If each one experiences a repulsive force equal to its weight find their separation.

Explanation

To solve the problem, we need to find the separation \( R \) between two positively charged particles, each experiencing a repulsive force equal to its weight. Here are the steps to arrive at the solution:

### Step 1: Identify the Forces
The electrostatic force \( F_E \) between the two charged particles is given by Coulomb's law:
\[ F_E = \frac{1}{4 \pi \epsilon_0} \frac{Q_1 Q_2}{R^2} \]
where \( Q_1 \) and \( Q_2 \) are the charges of the particles, and \( R \) is the separation between them.
