Question
In the scenarios listed below, find the direction of the force (if any) that will be exerted on the charge. A positive charge within an electric field that points to the right. A negative charge within an electric field that points upward. A positive charge moving out of the screen in a magnetic field that points upward. A negative charge moving into the screen in a magnetic field that points to the right. A positive charge moving downward in an electric field that points out of the screen. A negative charge moving into the screen in a magnetic field that points out of the screen.Explanation / Answer
1. Posive charge in electric fielf
F = qE , hereF is in the direction of E
Ans. to the Right
2. -ve charge in electric fielf
F = qE , here F is in opposite direction of E
Ans. to the left
3.Postive charge moving out in magnetic field upward
F = q(vXB) = q (v j x B k)
=qvb i
Ans. Force is to the right
4. -ve charge moving out in magnetic field upward
F = -q(vXB)
Ans. Force is to the left
5. +ve charge moving downward electric field point out of the screen,
F=qE
Direction force is same as electric field.
Ans. Points out of the screen.
6.-ve charge moving downward electric field point out of the screen,
F=-qE
Direction force is opposite as electric field.
Ans. into of the screen.
