Three-point charges are placed on the $\mathrm{x}$-axis, as follows. A charge of $4.5?\mathrm{C}$ is at the origin, a charge of $2.5?\mathrm{C}$ is at $\mathrm{x}=$ $56\mathrm{cm}$, and a charge of $4?\mathrm{C}$ is at $\mathrm{x}=62\mathrm{cm}$. What are the magnitude and direction of the electrostatic force on the charge at the origin due to the other two charges? $(k=1/4?{?}_0$ $=9.0\times 10^9\mathrm{N}?{\mathrm{m}}^2/{\mathrm{C}}^2$ ) Net force N Direction
