Answer:
The magnitude of Electric Field is 
Explanation:
Given:
- Radius of the solid sphere=R
- Total charge of the sphere=Q
Let consider a Gaussian surface at a distance of r such that 0<r>R in the shape of sphere such that the electric Field due to this E and it is radially outwards.
The charge inside this Gaussian surface volume we have , 
Now using Gauss Law we have

Answer:
10 159.8744 m
Explanation:
Hi there!
Since
<em> 1 mile = 1609.34 m</em>
and:
<em> 1 yard = 0.9144 m</em>
We have that:
<em>6 miles + 551 yards = 6 *(1609.34) + 551*(0.9144) m</em>
Therefore, the distance is (in meters):
d = 10 159.8744 m
Rounded to the first decimal
d = 10 159.9 m
