The Answer of SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.
Sketch the vector field in the plane along with its horizontal and vertical components at a representative assortment of points on the circle $x ^ { 2 } + y ^ { 2 } = 4$.
-$$F = \frac { y } { \sqrt { x ^ { 2 } + y ^ { 2 } } } \mathrm { i } + \frac { x } { \sqrt { x ^ { 2 } + y ^ { 2 } } } j$$

SHORT ANSWER x2+y2=4x ^ { 2 } + y ^ { 2 } = 4x2+y2=4

SHORT ANSWER $x ^ { 2 } + y ^ { 2 } = 4$
