The existence of the dwarf planet Pluto was proposed based on irregularities in Neptune's orbit.  Pluto was subsequently discovered near its predicted position.  But it now appears the discovery was fortuitous, because Pluto is small and the irregularities in Neptune's orbit were not well known.  To illustrate that Pluto has a minor effect on the orbit of Neptune, calculate the acceleration due to gravity at Neptune, in m/s2, due to Pluto when they are 4.50x1012 m apart, as they are at present.  The mass of Pluto is 1.4x1022 kg. Group of answer choices 4.6x10-14 5.7x10-15 6.8x10-16 7.9x10-17

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
