Two point charges are distance d = 59.3 cm apart, They have equal and opposite charge, each with magnitude Q = 8.62 µC. The negative charge is on the left, and the positive charge is on the right. An electron (mass 9.11 x 10-31 kg, charge 1.6 x 10-19 C) is placed half-way between the charges.
a) The electric field at this point is (in N/C)
b) The force on the electron is (in N)
