Q3) Two point charges (Q = + 5.0 µC and Q2 = – 2.0 µ C) are held in place along the x-axis. Q, is at x1 = - 3.0 cm and Q, is at x2 = + 2.0 cm. a) Determine the electric field at (x, y) = (0, 4.0 cm) in SI units. Represent your answer as a vector. Start with drawing a picture and setting up an appropriate coordinate system.

Question
Transcribed Image Text:Q3) Two point charges (Q = + 5.0 µC and Q2 = – 2.0 µ C) are held in place along the x-axis. Q, is at
x1 = - 3.0 cm and Q, is at x2 = + 2.0 cm.
a) Determine the electric field at (x, y) = (0,4.0 cm) in SI units. Represent your answer as a vector. Start with
drawing a picture and setting up an appropriate coordinate system.
b) Determine in what region along the x-axis it's possible for the electric field to be zero. There are three distinct
regions: -o < x < x1, X1 < x < x2, and x2 < x < ∞ (this excludes x → ±∞ since the electric field is zero
there).
c) Now that you know in what region it's possible for the electric field to be zero, write out an expression you
could solution to find exactly where this location is. Note: you DON'T have to solve it.
d) Another charge (Q3
Newtons? Represent your answer as a vector. Hint: no need to apply Coulomb's law to Q3, you already know the electric
field at this point.
4.0 µ C) is now placed at (x, y) = (0,4.0 cm). What is the net force on this charge in
