Final answer:
To calculate the electrostatic force of attraction between two objects, we can use Coulomb's Law. The force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Step-by-step explanation:
The electrostatic force of attraction between two objects can be calculated using Coulomb's Law. Coulomb's Law states that the force of attraction or repulsion between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Let's calculate the electrostatic force of attraction between John and Mary. The charges on John and Mary can be calculated by multiplying their weight by the percentage imbalance in charge. John's charge would be 92 kg * (0.0004) and Mary's charge would be 46 kg * (0.0004).
Using the charges calculated, we can use Coulomb's Law to find the force of attraction between them. F = k * (q1 * q2) / r^2, where k is the electrostatic constant, q1 and q2 are the charges of the objects, and r is the distance between them. Substituting the values, we can find the electrostatic force of attraction.
