Extracted text: Three identical point masses of m =0.2 (kg) are moving at a constant velocity v =20 (m/s) equidistant from each other on a circular orbit of radius R = 0.3 (m). What is the total angular momentum (kg.m²/s) of the three point masses relative to point A at the moment shown in the figure. Point A is 2R away from the center. m 2R m a: m A) 0.9 В) 1.2 С) 1.8 D) 3.0 E) 3.6
