A body of mass $m=10 \mathrm{~kg}$ is attached to a wire of length $0.3 \mathrm{~m}$. The maximum angular velocity with which it can be rotated in a horizontal circle is: (Breaking stress of wire $=4.8 \times 10^{7} \mathrm{~N} / \mathrm{m}^{2}$ and area of cross-section of a wire $\left.=10^{-6} \mathrm{~m}^{2}\right)$ (a) $4 \mathrm{rad} / \mathrm{s}$ (b) $8 \mathrm{rad} / \mathrm{s}$ (c) $1 \mathrm{rad} / \mathrm{s}$ (d) $2 \mathrm{rad} / \mathrm{s}$
A mass of 0.1 kg is tied to a rope of length 6 m. The maximum tension is 6.4 N. The mass is revolved in a vertical circular path. Find the maximum angular speed of the body. (g = 10 m/s^2)
