the answers on it is wrong, please i need the correct answer like asap, thank you

### Problem Description Three identical, very dense masses of 7400 kg each are placed on the x-axis. One mass is at \( x_1 = -150 \, \text{cm} \), one is at the origin, and one is at \( x_2 = 390 \, \text{cm} \). ### Question **Part A** What is the magnitude of the net gravitational force \( F_{\text{grav}} \) on the mass at the origin due to the other two masses? Take the gravitational constant to be \( G = 6.67 \times 10^{-11} \, \text{N} \cdot \text{m}^2/\text{kg}^2 \). **Express your answer in newtons to three significant figures.** - **Input Field:** \( F_{\text{grav}} = \underline{\quad 1.33 \times 10^{-3} \quad} \, \text{N} \) - **Submit Button** - **Previous Answers Link** ### Feedback **Incorrect; Try Again; 4 attempts remaining** Although the two masses not at the origin are identical, they are not the same distance from the origin, so there will be a nonzero net force on the mass at the origin.
