Class 12 physics Coulomb's law formula part 10 types of questions
Understand the Problem
The question is asking for a specific formula related to Coulomb's law in physics, along with 10 different types of questions that can be derived from it for Class 12 level study. The focus is on understanding the formula and its applications.
Answer
F = k * |q1*q2| / r²
Coulomb's law formula is F = k * |q1*q2| / r², where F is the force between charges, q1 and q2 are the magnitudes of the charges, r is the distance between them, and k is Coulomb's constant.
Answer for screen readers
Coulomb's law formula is F = k * |q1*q2| / r², where F is the force between charges, q1 and q2 are the magnitudes of the charges, r is the distance between them, and k is Coulomb's constant.
More Information
Coulomb's law describes the force between two charges. The force is inversely proportional to the square of the distance between the charges, and directly proportional to the product of their magnitudes.
Tips
Common mistakes include not squaring the distance and forgetting the vector nature of force (direction matters).
