$\mathrm { A } + 7.5 - \mathrm { nC }$ point charge is $5.0 \mathrm {~cm}$ from a $- 9.4 - \mu \mathrm { C }$ point charge in your laboratory in California. How much work would you have to do if you left the $+ 7.5 - \mathrm { nC }$ charge in the lab but took the $- 9.4 - \mu \mathrm { C }$ charge to New York City? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

The Answer of $\mathrm { A } + 7.5 - \mathrm { nC }$ point charge is $5.0 \mathrm {~cm}$ from a $- 9.4 - \mu \mathrm { C }$ point charge in your laboratory in California. How much work would you have to do if you left the $+ 7.5 - \mathrm { nC }$ charge in the lab but took the $- 9.4 - \mu \mathrm { C }$ charge to New York City? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$
