A ball of massm=0.5 kgis attached to the end of a string having lengthL= 0.5 mis rotated on a horizontal circular path about the vertical axis. The maximum tension that the string can bear is324 N. What is the maximum possible value of angular velocity of ball (inradian/s) ?

Options:

Answer:
D
Solution:

T sin θ = m ω 2 r

T sin θ = m ω 2 L sin θ

T = m ω 2 L

3 2 4 = 1 2 ω 2 1 2

Therefore ω = 3 6
