Three point masses \( m_{1}, m_{2} \) and \( m_{3} \) are located at the vertices of an equilateral triangle of side \( a \). What is the moment of \( \mathrm{P} \) inertia of the system about an axis along the altitude of the W triangle passing through \( m_{1} \) ? (1) \( \left(m_{1}+m_{2}\right) \frac{a^{2}}{4} \) (2) \( \left(m_{2}+m_{3}\right) \frac{a^{2}}{4} \) (3) \( \left(m_{1}+m_{3}\right) \frac{a^{2}}{4} \) (4) \( \left(m_{1}+m_{2}+m_{3}\right) \frac{a^{2}}{4} \) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
