A particle of mass 20 g is whirled into a vertical circle of radius 80cm using a massless string The speed of the particle when the string makes an angle 60^(@) with the verticle line is 1.5ms^(-1) What is the tension in the string in this position ?

A particle of mass 100 g, is made to describe a vertical circle of radius 1 m. Its instantaneous speed is 1ms^(-1) when the string makes an sngle of 30^(@) with the vertical Find the tension in the string at this position. Can the particle complete its circular path? (g=10ms^(-2))

A particle of mass 100 g, is made to describe a vertical circle of radius 1 m. Its instantaneous speed is 1ms^(-1) when the string makes an sngle of 30^(@) with the vertical Find the tension in the string at this position. Can the particle complete its circular path? (g=10ms^(-2))

A mass of 0.1 kg is rotated in a vertical circle using a string of legth 20 cm. When the string makes an angle 30^(@) with the vertical, the speed of the mass is 1.5ms^(-1) . The tangential acceleration of the mass at that instant is
