A point charge $Q _ { 1 } = + 6.0 \mathrm { nC }$ is at the point $( 0.30 \mathrm {~m} , 0.00 \mathrm {~m} )$; a charge $Q _ { 2 } = - 1.0 \mathrm { nC }$ is at $( 0.00 \mathrm {~m} , 0.10 \mathrm {~m} )$, and a charge $Q _ { 3 } = + 5.0 \mathrm { nC }$ is at $( 0.00 \mathrm {~m} , 0.00 \mathrm {~m} )$. What are the magnitude and direction of the net force on the $+ 5.0 - \mathrm { nC }$ charge due to the other two charges? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

The Answer of A point charge $Q _ { 1 } = + 6.0 \mathrm { nC }$ is at the point $( 0.30 \mathrm {~m} , 0.00 \mathrm {~m} )$; a charge $Q _ { 2 } = - 1.0 \mathrm { nC }$ is at $( 0.00 \mathrm {~m} , 0.10 \mathrm {~m} )$, and a charge $Q _ { 3 } = + 5.0 \mathrm { nC }$ is at $( 0.00 \mathrm {~m} , 0.00 \mathrm {~m} )$. What are the magnitude and direction of the net force on the $+ 5.0 - \mathrm { nC }$ charge due to the other two charges? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$
