A very long half-cylinder of radius r carries a total current is uniformly distributed across the circumference. Determine the m
1 answer:
The magnetic field along the central axis of the cylinder will be <em>determined </em>using the formula given that all parameters are known
Generally, A magnetic field is also referred to as a vector field that shows the magnetic presence on electric charges and magnetic materials.
The formula for magnetic field is
Where
Therefore, the magnetic field along the central axis of the cylinder will be determined using the formula given that all parameters are known

Answer:
QA = 19μC
QB = 9.5 μC
Explanation:
- The force that each charge exerts on the other must obey Coulomb's Law, as follows:
- We know that the value of the magnitude of FAB is 45.0 N, the distance between QA and QB is 0.19 m, and that QA = 2*QB.
- Replacing in (1), we can solve for QB, as follows:
- Since QA = 2*QB
- ⇒ QA = 2* 9.5μC = 19.0 μC
- ⇒ QB = 9.5μC
