List of top Physics Questions on tension

In a vertical circle of radius r, at what point in its path does a particle have tension equal to zero if it is just able to complete the vertical circle?
A box of mass 5 kg is pulled by a cord, up along a frictionless plane inclined at 30° with the horizontal. The tension in the cord is 30 N. The acceleration of the box is (Take g = 10 m s–2)
A bob is whirled in a horizontal plane by means of a string with an initial speed of ω rpm. The tension in the string is T. If speed becomes 2ω while keeping the same radius, the tension in the string becomes:
A monkey of mass 50 kg climbs on a rope which can withstand the tension \( T = 350 \, \text{N} \). If the monkey initially climbs down with an acceleration of \( 4 \, \text{m/s}^2 \) and then climbs up with an acceleration of \( 5 \, \text{m/s}^2 \), choose the correct option (\( g = 10 \, \text{m/s}^2 \)):
Two monkeys off mass 10 kg and 8 kg are moving along a vertical light rope the former climbing up with an acceleration of 2 m/second square while the latter coming down with a uniform velocity of 2 m/sec square find the tension in the rope at the fixed support
