Question
1. Two parallel currents repel each other.2. A horizontal wire containing a current toward the east will have a negative Hall potential from the bottom to the top of the wire.
3. A + charge initially moving west through the earths magnetic field along the equator will fall faster than if it is moving east.
4. The time required for a charged particle to complete one cycle of a circular path in a uniform magnetic field is independent of the velocity of the charged particle.
5. A horizontal wire containing a current toward the east will have a positive Hall potential from the bottom to the top of the wire.
Need to know why.. Thank you !
Explanation / Answer
1) If the currents in two parallel conductors are in opposite then only repel each other so it is true currents opposite directions 2)True due to majarity of electrons negative potential difference builds 3) False Because earths magnetic field along South to North which perpendecular to the motion of charge 4) True Formulae T=2m/Bq 5) False due to majarity of electrons negative potential difference buildsRelated Questions
