Answer:
The particle's velocity is 212.15 m/s.
Explanation:
Given that,
Charge of particle, ![q=6.41\ \mu C=6.41\times 10^{-6}\ C](https://tex.z-dn.net/?f=q%3D6.41%5C%20%5Cmu%20C%3D6.41%5Ctimes%2010%5E%7B-6%7D%5C%20C)
The magnitude of electric field, E = 1270 N/C
The magnitude of magnetic field, B = 1.28 T
Net force, ![F=6.4\times 10^{-3}\ N](https://tex.z-dn.net/?f=F%3D6.4%5Ctimes%2010%5E%7B-3%7D%5C%20N)
We need to find the magnitude of the particle's velocity. the net force acting on the particle is given by Lorentz force as :
![F=qE+qvB\\\\v=\dfrac{F-qE}{qB}\\\\v=\dfrac{6.4\times 10^{-3}-6.41\times 10^{-6}\times 1270}{6.41\times 10^{-6}\times 1.28}\\\\v=-212.15\ m/s](https://tex.z-dn.net/?f=F%3DqE%2BqvB%5C%5C%5C%5Cv%3D%5Cdfrac%7BF-qE%7D%7BqB%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B6.4%5Ctimes%2010%5E%7B-3%7D-6.41%5Ctimes%2010%5E%7B-6%7D%5Ctimes%201270%7D%7B6.41%5Ctimes%2010%5E%7B-6%7D%5Ctimes%201.28%7D%5C%5C%5C%5Cv%3D-212.15%5C%20m%2Fs)
So, the particle's velocity is 212.15 m/s.

Answer:
Ohms law
Explanation:
Which states that the current flowing through any cross-section of the conductor is directly proportional to the potential differenceapplied across its end, provided physical conditions like temperature and pressure remain constant.
