Answer:
The magnitude of electric force is 
Explanation:
Coulomb's Law:
The force of attraction or repletion is
- directly proportional to the products of charges i.e
- inversely proportional to the square of distance i.e
[ k is proportional constant=9×10⁹N m²/C²]
There are two types of force applied on Q=+2.5 μC=2.5×10⁻⁶ C
Let F₁ force be applied on Q =+2.5 μC by q₁= -5.0 μC = - 5.0×10⁻⁶ C
and F₂ force be applied on Q=+2.5 μC by q₂= 5.0 μC= 5.0×10⁻⁶ C
Since the magnitude of F₁ and F₂ are same. Therefore their y component cancel.
If we draw a line from q₁ to Q .
The it forms a triangle whose base = 4.0 cm and altitude =3.0 cm.
Let hypotenuse = r
Therefore, 
we know,
Total force 
[ r=5]
N
The magnitude of electric force is
it will experience great force
For the answer to te question above, it is a. The Electron Cloud.
For additional information, The Electron Cloud is an informal term in physics. It is used to describe where electrons are when they go around the nucleus of an atom.
I hope my answer helped you.
Answer:
0.336 rad/s
Explanation:
= Angular speed of the turntable = -0.2 rad/s
R = Radius of turntable = 2.9 m
I = Moment of inertia of turntable = 
M = Mass of turn table = 53 kg
= Magnitude of the runner's velocity relative to the earth = 3.6 m/s
As the momentum in the system is conserved we have
The angular velocity of the system if the runner comes to rest relative to the turntable which is the required answer is 0.336 rad/s
Answer:
Explanation:
Satellites experiment a force given by Newton's Gravitation Law:
where M is Earth's mass, m the satellite's mass, r the distance between their gravitational centers and G the gravitational constant.
We also know from Newton's 2nd Law that <em>F=ma, </em>so putting both together we will have:
If we are on the surface of the Earth, the acceleration would be g and 
(Earth's radius):
Which we will write as:
If we are on orbit the acceleration is centripetal (
), so we have:
And if this orbit has a radius 
we have:
