A ring of mass $2 π kg$ and of radius 0.25 m is making 600 rpm about an axis through its centre and perpendicular to its plane. The tension in newton developed in the ring is approximately

Options:

Answer:

Solution:

$T = 2 πm n^{2} R$
with $n = 10 rps$ :
$T = 2 π \times 2 π \times 100 \times 0.25 = 100 π^{2} \approx 1000 N .$
