A pendulum has a bob of mass m, which is held at rest horizontally as in the figure. The pendulum is connected to a wall by a string of length L The string has a negligible mass, but it is not very strong: it cannot withstand tensions greater than 2mg. If the bob is released and let go, at what heighth above the lowest point of its expected circular trajectory will the string break? L h h L hL The string will not break
