Two small identical blocks of mass 10 g carrying the same charge of magnitude 0.2 `muC` are kept at a separation of 0.1 m on a rough table . If both the blocks stay in equilibrium using limiting friction from the surface then calculate the coefficient of friction between the block and the table.

Explanation

To solve the problem, we need to determine the coefficient of friction between the blocks and the table. Here’s a step-by-step solution:

### Step 1: Identify the Given Data
- Mass of each block, \( m = 10 \, \text{g} = 0.01 \, \text{kg} \)
- Charge on each block, \( q = 0.2 \, \mu\text{C} = 0.2 \times 10^{-6} \, \text{C} \)
- Separation between the blocks, \( r = 0.1 \, \text{m} \)
- Gravitational acceleration, \( g = 10 \, \text{m/s}^2 \)
