Question

Two point charges are distance d = 30.8 cm apart, They have equaland opposite charge, each with magnitude Q = 8.46 µC. The negativecharge is on the left, and the positive charge is on the right. Anelectron (mass 9.11x10-31 kg, charge 1.6x10-19 C) is placedhalf-way between the charges.

1) The electric field at this point is
________ N/C

2) The direction of the electric field is:
a. into the page
b. left, toward the negative charge
c. upward
d. zero
e. right, toward the positive charge
f. out of the page
g. downward


3) The force on the electron is
______ N

4) The direction of the force on the electron is:
a. right, toward the positive charge
b. into the page
c. left, toward the negative charge
d. zero
e. upward
f. out of the page
g. downward
