Question

2kg mass is tied to a string at one end and rotated in horizontal circle of radius 1.145 m about the other end. if the breaking tension in the string is 350 Newtons find the maximum angular velocity at which the mass can be rotated​

Answer 1

Answer:

12.36 radian/sec

Explanation:

tension in the string = centripetal force

mv^2/R= tension

according to the question

2×r×omega^2= 350

omega^2= 350×1000/1145×2

= 152.8

therefore angular velocity= 12.36(approx)
