A ‘central’ force is always directed
- a)along the position vector of the point of application of the force with respect to the fixed point
- b)perpendicular to the position vector of the point of application of the force with respect to the fixed point
- c)at a fixed angle to the position vector of the point of application of the force with respect to the fixed point
- d)at a varying angle to the position vector of the point of application of the force with respect to the fixed point
Correct answer is option 'A'. Can you explain this answer?

The motion of a particle under a central force F always remains in the plane defined by its initial position and velocity.This may be seen by symmetry. Since the position r, velocity v and force F all lie in the same plane, there is never an acceleration perpendicular to that plane, because that would break the symmetry between "above" the plane and "below" the plane.
To demonstrate this mathematically, it suffices to show that the angular momentum of the particle is constant. This angular momentum L is defined by the equation
L=r×p=r×mv

A is the first letter of the English alphabet. It is a vowel and can also be used as an indefinite article, as in "a book" or "a car." In music, A is the symbol for the note A, which is commonly used as a reference pitch. In science, A can represent various elements, such as the element arsenic (As) or the universal gas constant (R). In everyday language, A can also be used as a prefix to indicate "not," as in "asexual" or "atheist."
