A particle, of mass 150 g, is attached to one end of a massless, inextensible string. It is made to describe a vertical circle of radius 1 m. When the string is making an angle of 48.2° with the vertical, its instantaneous speed is 2 m${{s}^{-1}}$. What is the tension in the string in this position ? Would this particle be able to complete its circular path ? (Take g = 10 ms-2)
