Calculate the electric field strength required to just support a water drop of mass `10^(-7)` kg and having a charge `1.6xx10^(-19)` C

Explanation

To calculate the electric field strength required to just support a water drop of mass \(10^{-7}\) kg and having a charge of \(1.6 \times 10^{-19}\) C, we can follow these steps:

### Step 1: Identify the forces acting on the water drop
The forces acting on the water drop are:
- The gravitational force (weight) acting downwards, given by \( F_g = mg \)
- The electrostatic force acting upwards, given by \( F_e = qE \)

Where:
