Solution:
We will work on the decomposition of the force vector here.
For 30 degree point, gravity pull the point down at 10 * 0.1 = 1N downwards. The string is under tension so it has 0.5 N going to the right and 0.866 N downwards
For 120 degree point, gravity pull the point down at 10 * 0.1 = 1N downwards, the string is not pulling it at all until it falls to a certain point
For 230 degree point, gravity pull the point down at 10 * 0.1 = 1N downwards, the string is not pulling it at all until it falls to a certain point
