Question

An electron can revolve around the nucleus and doesn't fall into it . Which force acts here? Explain.​

Answer 1

Answer:

Centripetal Force

Explanation:

• Centripetal force is the component of force acting on an object in curvilinear motion which is directed toward the axis of rotation or centre of curvature.

• The unit of centripetal force is Newton.

• The centripetal force is always directed perpendicular to the direction of the displacement of the object.

• If an object accelerates according to the changes of velocity, then it can change either its speed or direction of motion.

• In simple terms, if any moving object in a circular path is constantly changing its direction means it is constantly accelerating.

• Using Newton’s second law of motion, if an object is travelling in a circular path, it is found that the centripetal force of an object moving in a circular path always acts towards the centre of the circle.

• A few examples of Centripetal Force:

1. Spinning a ball on a string or twirling a lasso: Here the centripetal force is provided by the force of tension on the rope pulls the object in toward the centre.
2. Turning a car: Here the centripetal force is provided by the frictional force between the ground and the wheels.
3. Going through a loop on a roller coaster: The force is provided by the Normal Force as the seat or wall pushes you toward the centre.
4. Planets orbiting around the Sun: Centripetal Force is provided by Gravity.
