Two negative charges of 0.4 C and 0.2 C are separated by 20 m. What is the strength of the force acting on the particles? Group of answer choices 36,000,000 N 7,200,000 N 1,800,000 N 720,000,000 N

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

i do.
