Answer:
The point that would have the same electric field as P is from the center of the sphere.
Explanation:
From the question we are told that
The radius of the sphere is
The Electric field at point P is
The distance of point P from the center is
Since the electric is directed radially outward it mean this it would be felt both inside and outside the sphere
The Electric field inside the sphere at a distance z is mathematically represented as
where k is the coulomb's constant with a value
q is the charge
The Electric field inside the sphere at a distance D is mathematically represented as
To obtain the point of equal electric field
We have that
Substituting values
Answer:
340 m/s
Solution:
As per the question;
Time, t = 3.0 s
Total distance moved by the ship, d = 10,500 km
The increase in speed, v = 340 m/s
Now,
To calculate the U.S.S Burger's change in speed, :
The final velocity is given by:
(1)
where
Also, the change in velocity is given by:
(2)
Now, from eqn (1) and (2):
