Homework Statement
The below region of space shown has uniform electric and/or magnetic fields, dependent on the conditions listed for cases A-G. Identical positively charged particles enters these regions with the same velocity.
Rank the magnitude of the force on the particle just after it enters these regions for cases A-G from greatest to least.
Homework Equations
F = qE + qv x B
F = qE
Fb = qvBsin(*)
The Attempt at a Solution
A) Since the particle is positive(+) I said there would be a force F namely ( ---> ) on the particle.
B) When only B is present there is no force on the particle, Fb = qvBsin(0) = 0. This is because both B and V are parallel.
C) Same as A: ( ---> )
D) Same as A: ( ---> )
E) Here the direction of the force changes but its magnitude remains the same so: ( <--- )
F) There is an upwards force in this case. However, its magnitude is the same as was in A.
G) I have this as being two forces on the particle so G is the largest.
Overall I ranked them as follows: G>A=C=D=E=F>B
Not sure if I did these correctly any help would be appreciated.
