Explanation:
It is given that,
Speed of the electron in horizontal region, 
Vertical force, 
Vertical acceleration, 
..........(1)
Let t is the time taken by the electron, such that,
...........(2)
Let 
is the vertical distance deflected during this time. It can be calculated using second equation of motion:
u = 0
So, the vertical distance the electron is deflected during the time is 0.426 mm. Hence, this is the required solution.
Answer:
I can help with the last question.
Explanation:
The force from the ball on the left ball will hit the ball next to it, bringing the force all the way to the right ball, and vice versa. Have a great day!
Answer:
the direction of the particle is anti clockwise.
Explanation:
We know that;
- It's a positive particle
- That it's moving in a circle in a magnetic field
- We know the direction of the magnetic field
We can deduce the direction of the magnetic force because it is moving in a circle.
So the force is pointing to the centre of the circle and that's what is keeping it in that circular motion.
Since we know the direction of the magnetic field and force, we can use right hand rule to figure out the direction of the particle since the particle is positive.
Using right hand rule, the thumb which is the particle is pointing anticlockwise. So the direction of the particle is anti clockwise.
