Question

A vector field F has the property that the flux of F out of a small cube of side 0.01 centered around the point (2, 9, 11) is 0.002. Estimate div F at the point (2, 9, 11).

div F =

Answer 1

@ganeshie8 can you help me with this one plese

Answer 2

divide flux by the volume

Answer 3

\[\large \dfrac{0.002}{0.01^3}\]
