Answer:
Right Hand Rule
Explanation:
When a charged particle travels in a magnetic field, it experiences a force whose magnitude is given by:
where
q is the charge of the particle
v is the velocity
B is the magnetic field strength
is the angle between the directions of v and B
The direction of the force can be determined by using the Right Hand Rule, as follows:
- index finger: this should be put in the direction of the velocity
- middle finger: this should be put in the direction of the magnetic field
- thumb: this will give the direction of the force -> however, for a negative charge (as the electron) the direction must be reversed, so it will be opposite.
Answer:
3.2 × 10⁻⁸ N.
Explanation:
By Coulomb's Law, the magnitude of the electromagnetic force between two point charges is inversely proportional to the square of their separation, . In other words,
.
- Initial electromagnetic force
;
- Initial Separation
;
- Final Separation
.
Final electromagnetic force:
.
Answer:
Explanation:
We have in the problem the following expression,
Where
c= cost in dollar
p= is percent of stream (Which )
P must be greater or equal to 0 but as well must be less than 100%
so we define the interval
If the value were equal to 100 the cost would be the equivalent of 0 and there would be no profit / gain.
