How exactly do you get those answers? Also, the program says those are not the right answers.
Never mind. i figured it out. the diagram didn't even come out right anyways. Tension(T)=mu_static(μ_s)* mass(m)* gravity(g) T=.65(20)(9.8)= 127.4 N T=m(g) 127.4=m(9.8) m=13 kg for block A
I forgot the questions. What is the magnitude of F⃗ elec? What is the tension in the string?
