Answer (1 of 3): The tension T will be constant at any position if we assume a constant speed v of the stone. The tension T is the result of the Force F needed to make a circular movement. This Force F is caused by an acceleration a. (Remark: a, F,. v / m s−1 a/ m s−2 A 0.021 0.18 B 8.4 0.088 C 8.4 0.18 D 17 0.35 (Total 1 mark) Q15. The figure shows a smooth thin tube T through which passes a string with masses m and M attached to its ends. Initially the tube is moved so that the mass, m, travels in a horizontal circle of constant radius r, at constant speed, v.
