Answer:
.
Explanation:
Since no external force is acting on the system.
Therefore, Total energy remains constant before and after.
So, Total energy of system= energy due to potential applied+kinetic energy
(Here v=velocity ,V=potential ,q=charge and m=mass).
Putting values .
We get, .
At point B charged particle is moving faster as compared to point A.
Hence, it is the required solution.
Answer:
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
Unit: Pascal (Pa)
1Pa = 1N/m^2
It means that acceleration changes with time.
Well talking , reading and writing are the tri skills merging for regular communication . It is most crucial to learn how to behave in a disciplined environment .Trying to help a person who does not speak the same language that you do won't be a rose walk journey . Learn to think and write complete things related to skill development and shape your personality .
Stamina to rejuvenate and think with more alacrity arouses when you read your confidence. Character sketching is one of the solution greatly can impact on thinking abilities and speaking art. Language is not just the soul of the communication but also holds integral part to satire public and attract them.

Answer:
Explanation:
Given that:
thickness of the metal strip, 
width of the metal strip, 
magnitude of the perpendicular magnetic field, 
current through the strip, 
charge density, 
Hall voltage is a transverse voltage given by:
putting the respective values
Note:
V = E d is used when a charge is moved in a uniform electric field between the two oppositely charged plates, it can't be used here because it is the case of Hall effect where the small voltage develops transverse to the direction of current flow.
