Question

Determine the direction of the force (if any) that will act on the charge in each of the following situations:

1 A positive charge within an electric field that points to the right.

2 A negative charge within an electric field that points downward.

3 A positive charge moving downward in a magnetic field that points out of the screen.

4 A negative charge moving to the right in a magnetic field that points into the screen.

5 A positive charge moving upward in an electric field that points into the screen.

6 A positive charge moving upward in a magnetic field that points upward.

Choices: into the screen, out of the screen, zero force, to the right, to the left, upward, downward

part a )

towards right , because direction of force from charge is always away from charge .

part b )

downwards . force direction always towards negative charge

part c )

by right hand rule , it towards left

part d )

downward for negative charge it opposite

part 5 )

in direction of electric field = into the screen

part 6 )

zero

both v and B in same direction

F = q ( v x B)

sin theta = 0 F = 0
