Question

A body of mass 10 kg is attached to a wire of radius
3 cm. It’s breaking stress is 4.8 × 10⁷ Nm⁻², the area
of cross-section of the wire is 10⁻⁶ m². What is the
maximum angular velocity with which it can be
rotated in the horizontal circle?
(a) 1 rad sec⁻¹ (b) 2 rad sec⁻¹
(c) 4 rad sec⁻¹ (d) 8 rad sec⁻¹
