The tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
<h3>
Tension in the cable</h3>
The tension in the cable supporting the swing of the ball is calculated as follows;
T = mg + mac
T = mg + m(v²)/r
T = (4810 x 9.8) + (4810 x 1.06²)/12.3
T = 47,577.4 N
Thus, the tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
