i is the x-component and for some reason the answer is 14i N/C, but i don't know why

Thanks, figured it out.

Electric field at distance r for each charge E=Kq/r^2 E_1=(9.0*10^9)(6*10^-9)/r^2 E_1 = 54/r^2 E_2=(9.0*10^9)(1*10^-9)/r^2 E_2 = 9/r^2 E_net = E_1+E_2 = 54/r^2 + 9/r^2 E_net = (54+9)(1/r^2) E_net = 63/r^2 0 = 63/r^2

Homework Statement a 6uC + charge is at (0,0) and a 1uC + charge is at (0,1m). Where between them is the electric field equal to 0? Homework Equations F=qE F=K(q_1)(q_2)/r^2 The Attempt at a Solution F=K(q_1)(q_2)/r^2 F=(9.0*10^9)(1*10^-6)(6*10^-6)/(1^2) F=5.4*10^-5 (The force...

Homework Statement A 4C charge experiences 45i of force. What is the electric field at the charge? Homework Equations F=qE --> E=F/q The Attempt at a Solution Q=4 F=45i 0j I don't really know how to find the actual force from this component without an angle or anything...

Homework Statement An equilateral triangle is formed with 3 rods, each with a length of 10cm. Two of them carry a charge of +63nC and 1 carries a charge of -63nC. The charge is uniformly distributed along each rod. What is the magnitude of the electric field at the center of the triangle...
