A toy aircraft (without an engine) is attached to the end of a 20 cm long weightless cable. A person holding the other end of t cable starts to spin the cable so that the aircraft starts to fly in a circular path on a horizontal plane. Mass of the aircraft is 125 g. (a) If the spinning cable along with the aircraft moves in a horizontal plane parallel to the ground as the plane reaches a uniform speed of 10 m/s, what is the tension on the cable? (b) If the person spins the cable at a lower speed while holding their end of the cable in the same place as before, the aircraft will now rotate in a horizontal plane closer to the ground than before (i.e. the cable will no longer stay horizontal to the ground). Find the Tension of the cable when the plane is moving at a speed of 5 m/s. (e) Find the angle between the cable and the herizontal plane. for the case described in part (e).

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.
