Question 56

Multiple Choice

Find the potential function f for the field F.
- F=xz2x2+y2i+yz2x2+y2j2x2+y2z3kF = \frac { x } { z ^ { 2 } \sqrt { x ^ { 2 } + y ^ { 2 } } } \mathbf { i } + \frac { y } { z ^ { 2 } \sqrt { x ^ { 2 } + y ^ { 2 } } } j - \frac { 2 \sqrt { x ^ { 2 } + y ^ { 2 } } } { z ^ { 3 } } \mathbf { k }


A) f(x,y,z) =x2+y2z2+Cf ( x , y , z ) = \frac { \sqrt { x ^ { 2 } + y ^ { 2 } } } { z ^ { 2 } } + C
B) f(x,y,z) =x2+y2+lnz+Cf ( x , y , z ) = \sqrt { x ^ { 2 } + y ^ { 2 } } + \ln z + C
C) f(x,y,z) =1z2x2+y2+Cf ( x , y , z ) = \frac { 1 } { z ^ { 2 } \sqrt { x ^ { 2 } + y ^ { 2 } } } + C
D) f(x,y,z) =x+yz2x2+y2+Cf ( x , y , z ) = \frac { x + y } { z ^ { 2 } \sqrt { x ^ { 2 } + y ^ { 2 } } } + C
