I got the first part, but the second part I having problems
with. Please help! Thanks in advance! =) Three charges are
arranged in a triangle as shown. 1) What is the net
electrostatic force on the charge at the origin? The Coulomb
constant is 8.98755 × 109 N · m2/C2. Answer in units of N. My
answer = 9.886^10-6 2) What is the direction of this force (as
an angle between -180? and 180? measured from the positive
x-axis, with counterclockwise Answer in units of degrees.
