Multiple Choice

Find the potential function f for the field F.
- $$\mathbf { F } = - \left( \frac { \mathrm { x } } { \left( \mathrm { x } ^ { 2 } + \mathrm { y } ^ { 2 } + \mathrm { z } ^ { 2 } \right) ^ { 3 / 2 } } \right) \mathbf { i } - \left( \frac { \mathrm { y } } { \left( \mathrm { x } ^ { 2 } + \mathrm { y } ^ { 2 } + \mathrm { z } ^ { 2 } \right) ^ { 3 / 2 } } \right) \mathbf { j } - \left( \frac { \mathrm { z } } { \left( \mathrm { x } ^ { 2 } + \mathrm { y } ^ { 2 } + \mathrm { z } ^ { 2 } \right) ^ { 3 / 2 } } \right) \mathbf { k }$$

• A) \(f ( x , y , z ) = - \frac { 1 } { \sqrt { x ^ { 2 } + y ^ { 2 } + z ^ { 2 } } } + C\)
• B) \(f ( x , y , z ) = \frac { 1 } { \sqrt { x ^ { 2 } + y ^ { 2 } + z ^ { 2 } } } + C\)
