Question
Part A
Find the magnitude of the force on a +0.16 C charge moving southward at 4.0 m/s .
Express your answer to two significant figures and include the appropriate units.
Part B
Find the direction of the force on a +0.16 C charge moving southward at 4.0 m/s
Part C
Repeat part A for a –0.16 C charge with the same velocity.
Express your answer to two significant figures and include the appropriate units.
Part D
Repeat part B for a –0.16 C charge with the same velocity.
A.pointing up
B.pointing down
Explanation / Answer
Magnetic field, B = 0.55 T (east)
speed of charge, v = 4 m/s (south)
charge, q = + 0.16 uC = 0.16 x 10^-6 C
A) mangitude of force on charge = q v B sin(theta) = 0.16 x 10^-6 x 0.55 x 4 x sin(90 deg) = 3.52 x 10^-7 N
B) Direction of force is directed upward using Flwmings left hand rule
Answer is A. pointing up
C) mangitude of force on charge = q v B sin(theta) = 0.16 x 10^-6 x 0.55 x 4 x sin(90 deg) = 3.52 x 10^-7 N
D) Direction of force is directed downward using Flwmings left hand rule
Answer is B. pointing down
