Problem

0.1\,\text{kg}

particle is attached to a string of length

1\,\text{m}

and rotated in a vertical circle. The string has a breaking tension of

10\,\text{N}

. Calculate the maximum possible velocity the particle can have at the lowest point of its path without breaking the string. Take

g = 10\,\text{m/s}^{2}
