I SAY IT IS A...............
The field is
<em><u>E</u></em> = 1 / (4 pi ε₀) Q / <em><u>R</u></em>² directed radially outward from
the center of the shell.
R is the radius of the spherical shell.
Notice that the field is exactly the same as the field due to a point-charge
with magnitude 'Q' that's located at the center of the sphere.
Answer:
The skier's change in velocity is 7.69 meters per second.
Explanation:
The Newton's second law tells force is equal to the change on the linear momentum of a body:

If we approximate the differential
to
:

Using that linear momentum is mass times velocity:

Solving for
:
