For two electron Fg/Fe = 10-43 i.e. gravitational force is negligible in comparison to electrostatic force of attraction.
Read the assertion and reason carefully to mark the correct option ou...
Explanation:
Assertion: Gravitational force between two particles is negligibly small compared to the electrical force.
Reason: The electrical force is experienced by charged particles only.
The correct answer is option 'B' - If both the assertion and reason are true but the reason is not the correct explanation of the assertion.
Explanation:
Gravitational Force:
- Gravitational force is the force of attraction between two objects due to their mass.
- It is a universal force and acts between any two objects in the universe.
- The gravitational force is always attractive and depends on the masses of the objects and the distance between them.
- The formula for calculating gravitational force is given by Newton's Law of Universal Gravitation: F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.
Electrical Force:
- Electrical force is the force of attraction or repulsion between two charged particles.
- It is also known as the electrostatic force.
- The electrical force can be attractive (opposite charges) or repulsive (like charges).
- The electrical force depends on the charges of the particles and the distance between them.
- The formula for calculating electrical force is given by Coulomb's Law: F = k * (q1 * q2) / r^2, where F is the electrical force, k is the electrostatic constant, q1 and q2 are the charges of the particles, and r is the distance between them.
Explanation of the Assertion and Reason:
- The assertion states that the gravitational force between two particles is negligibly small compared to the electrical force.
- This is because the electrical force is much stronger than the gravitational force.
- The reason given is that the electrical force is experienced by charged particles only.
- This reason is not the correct explanation of the assertion because the gravitational force is also experienced by all objects with mass, not just charged particles.
- The gravitational force acts between any two objects in the universe, regardless of their charge.
Conclusion:
- The assertion is true as the gravitational force is indeed much weaker compared to the electrical force.
- However, the reason is false as the gravitational force is experienced by all objects with mass, not just charged particles.
- Therefore, the correct answer is option 'B' - If both the assertion and reason are true but the reason is not the correct explanation of the assertion.
