For motiion of planets in ellipticla orbits around the sun the central force isA. the force on the plantet along the vector joining the sun and the planetB. the force on the sun along the vector joining the sun and the other focus of the ellipseC. the force on the planet along the line joining focus of the ellipseD. none of the above |

Answer» Correct Answer - A The central force is always directed towards or away from a fixed point i.e along the position vector of the point of application of the force with respect to the fixed point further the magnitude of a central force F depends on r the distance of the point of appication of the force from the fixed point F=F(r) For motion of planets in elliptical orbits around the sun the central force acts alongs the vector joining the sun and the planet |
