# A boy and a girl are balanced on a massless seesaw. The boy has a mass of \(60 \, \text{kg}\) and the girl’s mass is \(50 \, \text{kg}\). If the boy sits \(1.5 \, \text{m}\) from the pivot point on one side of the seesaw, where must the girl sit on the other side for equilibrium?

A boy and a girl are balanced on a massless seesaw. The boy has a mass of \(60 \, \text{kg}\) and the girl’s mass is \(50 \, \text{kg}\). If the boy sits \(1.5 \, \text{m}\) from the pivot point on one side of the seesaw, where must the girl sit on the other side for equilibrium?

- **A.** \(1.2 \, \text{m}\)
- **B.** \(1.3 \, \text{m}\)
- **C.** \(1.8 \, \text{m}\)
- **D.** \(2.5 \, \text{m}\)
- **E.** \(3.0 \, \text{m}\)
