Two identical balls having equal positive charge q coulomb are suspended by two in painting strings of equal length. What would be the effect on the force when a plastic sheet is inserted between the two?

Explanation

To solve the problem, we need to analyze the situation involving two identical balls with equal positive charges and the effect of inserting a plastic sheet between them. Here’s a step-by-step solution:

### Step 1: Understand the Initial Setup
We have two identical balls, each with a positive charge \( q \), suspended by strings of equal length. The electrostatic force \( F \) between the two charges can be described by Coulomb's Law:
\[ F = \frac{k \cdot q_1 \cdot q_2}{r^2} \]
where \( k \) is Coulomb's constant, \( q_1 \) and \( q_2 \) are the charges, and \( r \) is the distance between the charges.
