On the surface of a planet, you step on a bathroom scale and observe a reading of 180 N. You then board a de-elevator that goes to the center of the planet. On the way down, you stop, weigh yourself again and observe a reading of 50 N. How far below the planet's 'sea level' have you decended in km? Assume the planet radius and mass are 2370 km and 2.8 E23 kg, respectively.

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.
