2. The magnitude of each charge is calculated to be .
See the step by step solution

Equation

## Part (a) Step 2: Explanation

By comparing the given equation from the equation of the electrostatic force given by two identical point charges which is given as:

We get,

Electrostatic force

Separation of point charges

Constant

Hence, it can be concluded that the electrostatic force of is generated with two identical charges at a distance of .

## Part (a) Step 3: Final answer

Hence, the realistic problem that can be generated for the given question is:

If the electrostatic force acting between two identical charges separated by a distance of is , calculate the magnitude of each charge.

Equation

## Part (b) Step 2: Calculation

The given equation is:

Based on the equation, a realistic problem can be made as:

If the electrostatic force acting between two identical charges separated by a distance of is , calculate the magnitude of each charge.

Hence, by rearranging the terms to get the value of q,

## Part (b) Step 3: Final answer

Hence, the magnitude of each charge is calculated to be .
