A boy whirls a string of length 2 m around in an (almost) horizontal plane. At the end of the string a mass M₂ = 0.1 kg is fastened, and 1 m from the boy's hand another mass M₁ 0.1 kg is fastened. The boy increases the angular velocity w in the motion of the string. The hand of the boy and the two masses will, when w is sufficiently large, be almost on a straight line. When the string force reaches the magnitude 327 N, the string will break. (1) Find the magnitude of the angular velocity when the string breaks, and find where the break occurs. (2) Is it possible to whirl the two masses in such a way that the two masses on the string are exactly on a horizontal line?​ For correct answer with explaination, I'll mark him as the brainliest. (w is the angular velocity)
