PLZ HELP PLZZ What is the electric force acting between two charges of -0.0080 C and
0.0050 C that are 0.035 m apart? Use

and k = 9.00 x 109 N·m2/C2.
O A. 1.0 x 107 N
B. -1.0 x 107 N
O C. 2.9 x 10' N
O D. -2.9 x 108 N

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
