Answer: Try C
Explanation:
It's the only one that makes since.
Answer:
Towards the west
Explanation:
Magnetic force is the interaction between a moving charged particle and a magnetic field.
Magnetic force is given as
F = q (V × B)
Where F is the magnetic force
q is the charge
V is the velocity
B is the magnetic field
V×B means the cross product of the velocity and the magnetic field
NOTE:
i×i=j×j×k×k=0
i×j=k. j×i=-k
j×k=i. k×j=-i
k×i=j. i×k=-j
So, if the electron is moving southward, then, it implies that the velocity of it motion is southward, so the electron is in the positive z-direction
Also, the electron is curved upward due to the magnetic field, this implies that the force field is directed up in the positive y direction.
Then,
V = V•k
F = F•j
Then, apply the theorem
F •j = q ( V•k × B•x)
Let x be the unknown
From vector k×i =j.
This shows that x = i
Then, the magnetic field point in the direction of positive x axis, which is towards the west
You can as well use the Fleming right hand rule
The thumb represent force
The index finger represent velocity
The middle finger represent field
a.) the belief that stars and planets revolve around the earth
Explanation:
The geocentric model of stars and planets is the belief that stars and planets revolves around the earth.
The model places the earth at the center of the system.
- Geo - earth ; centric - center
- This was the original school of thought about the way the earth relates to other bodies in the universe.
- This model was replaced by the heliocentric universe in which stars are at the center and the planets revolves round them.
- The idea was put forward by Nicola Copernicus
