Field and force with three charges arrows representing the various electric field contributions, and then check the signs of your components against these arrows. Let \( Q_{1}=1 \mu \mathrm{C}, Q_{7}=6 \mu \mathrm{C} \), and \( Q_{3}=-6 \mu \mathrm{C} \). (a) Find the electric field at the location of \( Q_{1} \), due to \( Q_{2} \) and \( Q_{3} \). \[ \overrightarrow{\mathrm{E}}=\left.2.1 \cdot 10^{7}\right|_{\mathbf{x}} \mathrm{N} / \mathrm{C} \] (b) Use the electric field you calculated in part (a) to find the force on \( Q_{1} \). \[ \overrightarrow{\mathrm{F}}=\quad \mathrm{N} \] (c) Find the electric field at location \( A \), due to all three charges. \[ \overrightarrow{\mathrm{E}}=\text { Your answer cannot be understood or graded. More Information } \mathrm{N} / \mathrm{C} \] \( 10^{-27} \mathrm{~kg} \) for the mass of \( \mathrm{He}^{7+} \).) \[ \overrightarrow{\mathbf{a}}=\quad \mathrm{m} / \mathrm{s}^{2} \]
