Question:

From the figure, find out the perpendicular distance of the centre of mass of the system from side AB. ABCD is a square of side 2 m.

Options:

0.33 m

1.5 m

1 m

1.33 m

Correct Answer:

1.33 m

Explanation:

To find the perpendicular distance, we only need to find the y-coordinate.

Sum of masses = 4 + 4 + 2 + 2 = 12 kg

y-coordinate : (2 x 0 + 4 x 2 + 4 x 2 + 2 x 0)/12 = 1.33 m.
