A bomb of mass `m` at rest at the coordinate origin explodes into three equal pieces. At a certain instant one piece is on the x-axis at `x=60cm` and another is at `x=40cm, y=60cm`. The position of the third piece is

Options

A. `x = -100 cm , y = - 60 cm `
B. `x = - 60 cm , y = -60 cm `
C. `x = - 60 cm , y = 60 cm `
D. `x = 60 cm , y = -60 cm `

Answer

A

Explanation

`(x_cm ,y_cm)= (0,0), 0 = (m_(1)x_(1)+m_(2)x_(2)+m_(3)x_(3))/(m_(1)+m_(2)+m_(3))`
