Question

Three point particles of masses 1.0 k g , 1.5 kg and 2.5 k g are placed at three corners of a right angle triangle of sides 4.0 c m , 3.0 c m and 5.0 c m as shown in the figure. The centre of mass of the system is at a point:, 0.6 c m right and 2.0 c m above 1 k g mass., 1.5 c m right and 1.2 c m above 1 k g mass., 2.0 c m right and 0.9 c m above 1 k g mass., 0.9 c m right and 2.0 c m above 1 k g mass.

MARKS App · Accepted Answer

Take 1 k g mass at origin X c m = 1 × 0 + 1.5 × 3 + 2.5 × 0 5 = 0.9 c m Y c m = 1 × 0 + 1.5 × 0 + 2.5 × 4 5 = 2 c m
