Answer:
When reviewing the results, the correct one is C
Explanation:
The right hand rule is widely useful in knowing the direction of force in a maganto field,
The ruler sets the thumb in the direction of the positive particle, the fingers extended in the direction of the magnetic field, and the palm in the direction of the force.
Let's apply this to our exercise.
The thumb that is the speed goes in the negative direction of the axis,
The two extended that the magnetic field look negative x,
The span points entered the dear sheet the negative the Z axis
When reviewing the results, the correct one is C
Answer:
2.2 meters
Explanation:
Potential energy, PE created by a charge, q at a radius r from the charge source, Q, is expressed as:
![KE=\frac{kQq}{r}\ \ \ \ \ \ \ ...i](https://tex.z-dn.net/?f=KE%3D%5Cfrac%7BkQq%7D%7Br%7D%5C%20%20%20%20%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20...i)
is Coulomb's constant.
#The electric field,
at radius r is expressed as:
![E=\frac{kQ}{r^2}\ \ \ \ \ \ \ \ \ \ ...ii](https://tex.z-dn.net/?f=E%3D%5Cfrac%7BkQ%7D%7Br%5E2%7D%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20...ii)
From i and ii, we have:
![KE=Eqr](https://tex.z-dn.net/?f=KE%3DEqr)
![r=(KE)/Eq](https://tex.z-dn.net/?f=r%3D%28KE%29%2FEq)
#Substitute actual values in our equation:
![r=\frac{75J}{(7.2\times 10^{-5}C)(4.8\times 10^5 V/m)}\\\\=2.1701\approx2.2\ m](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B75J%7D%7B%287.2%5Ctimes%2010%5E%7B-5%7DC%29%284.8%5Ctimes%2010%5E5%20V%2Fm%29%7D%5C%5C%5C%5C%3D2.1701%5Capprox2.2%5C%20m)
Hence, the distance between the charge and the source of the electric field is 2.2 meters

Answer:
option c
Explanation:
The temperature must be constant. Ohms law states that the current running through a conductor is directly proportional to the potential difference across it provided the temperature remains constant
