A body of mass is attached to a wire of length. The breaking stress is . The area of cross-section from the wire is . The maximum angular velocity with which it can be rotated in a horizontal circle is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
The braking tension force for the wire is, F=σ·A ⇒F=4.8×107 N m-210-6 m2⇒F=48 N Now, the tension force will provide the necessary centripetal force so that it can rotate in a horizontal circle,…
