Thread: estimate divF

A vector field has the property that the flux of out of a small cube of side 0.01 centered around the point (2, 9, 11) is 0.003. Estimate div at the point (2, 9, 11).

Can someone help me how to start this problem off?

Flux = volume integral of divergence

if the cube is small divF is approx constant

Flux = divF*Volume

ok so :

divF = flux/volume...

= 0.003/(0.01)^3

= 3000

hope this is this correct

you got it
