A bob of mass 10 kg is attached to wire 0.3 m long. Its breaking stress is 4.8 × 10 7 N/m 2 . The area of cross section of the wire is 10 –6 m 2 . The maximum angular velocity with which it can be rotated in a horizontal circle
Text Solution
Verified by ExpertsThe correct answer is:
B
Centripetal force = breaking force
⇒ ⇒ 
breaking stress ´ ´ cross sectional area
⇒ ⇒ 
⇒ ⇒
