The sphere has a constant potential. It is the electric field.
In the sphere, then
Outside the sphere, then
The elements of the electric field include
Which becomes,
<h3>
In a consistent electric field, is force constant?</h3>
Similar to an ordinary object in the uniform gravitational field near the Earth's surface, a charged item in a uniform electric field experiences a constant force and consequently experiences a uniform acceleration. The vector cross product of p and E determines the torque's direction.
If the charge is positive, the force either moves in the same direction as E or in the opposite direction (if charge is negative).
A torque is experienced by an electric dipole (p) in an even electric field (E). The vector cross product of p and E determines the torque's direction.

Answer:
40.3 m/s
Explanation:
We'll begin by calculating the resultant force.
Resultant force = 2000 – 1000 = 1000N
Next we shall determine the acceleration of the car. This is illustrated below:
Mass of the car = 2000kg
Resultant Force = 1000N
Acceleration =.?
Resultant Force = Mass x Acceleration
1000 = 2000 x Acceleration
Divide both side by 2000
Acceleration = 1000/2000
Acceleration = 0.5m/s²
Finally, we shall determine velocity of the car when it has moved 1000m.
Initial velocity (u) = 25m/s
Acceleration (a) = 0.5m/s²
Distance (s) = 1000m
Final velocity (v) =..?
Applying the formula v² = u² + 2as we can obtain the velocity of the car at 1000m as follow:
v² = u² + 2as
v² = 25² + 2(0.5 x 1000)
v² = 625 + 2(500)
v² = 625 + 1000
v² = 1625
Take the square root of both side
v = √1625
v = 40.3 m/s
Therefore, the speed of the car when it has moved 1000m is 40.3 m/s
Answer:
The answer is B.
Explanation:
Hurricanes are known to cause strong storms and heavy flooding.
Answer:
The answer to your question is: a = 2 m/s²
Explanation:
I' ll solve it in this way, tell me if I'm right. Because we need to consider that in the moon there is no gravity.
Data
F = 50 N
a = 4.0 m/s²
Moon
F = 25 N
a = ?
Formula
F = m x a
First, calculate the mass
m = F / a
m = 50 / 4
m = 12.5 kg
Now, calculate the acceleration
a = F / m
a = 25 / 12.5
a = 2 m/s²
Answer:
I'm pretty sure that it's -225, hope this helps
