Question:

Two bodies of masses 5kg and 15kg are located in the cartesian plane at (1,0) and (0,1). What is the location of their centre of mass?

Options:

3/4, 3/4

3/4, 1/4

1/4, 1/4

1/4, 3/4

Correct Answer:

1/4, 3/4

Explanation:

Sum of masses = 5 + 15 = 20

x-coordinate : (5 x 1 + 15 x 0)/20 = 1/4

y-coordinate : (5 x 0 + 15 x 1)/20 = 3/4
