Question

A small sphere of radius 0.1 surrounds the point
(3, 5, −1).
The flux of a vector field
G
into this sphere is
0.00002π.
Estimate
div G
at the point
(3, 5, −1).
(Round your answer to three decimal places.)
div G=

Answer 1

@ganeshie8 do I do the same here flux/volume?

Answer 2

guess not :/

Answer 3

Yep!

Answer 4

well I got .015 but I got it wrong

Answer 5

\[Div F=\frac{ flux~out~of~the~region }{ volume}\]
u should use this

Answer 6

.00002pi/((4/3)pi(.1)^3

Answer 7

i did

Answer 8

i got .015 but its marking it wrong

Answer 9

@ganeshie8

Answer 10

try -0.015

Answer 11

since the flux given was into the sphere, the point was assumed to be a sink

Answer 12

oh yeah its negative

Answer 13

thanks @ganeshie8
