could anyone help me out with my Physics problem it has five parts.
You'll need a couple equations and a constant: \[F =kQ _{1}Q _{2}/d ^{2}\] k=9.0 x 109 N•m2/C2 That should get you through the first 2 questions. V=IR, P=VI \[R _{t}=R _{1}R _{_{2}}R _{3}/(R _{1}+R _{_{2}}+R _{3})\] Which should answer the next three.
#1 & #2: As said by mcgyver \[k=9*10^9\] #3 R=(R1*R2*R3)/(R1*R2+R2*R3+R3*R1) #4 I=V/R #5 P=V*I
1) the value is 9*10^9 and unit is Nm^2/C^2 2) the force between them is 23.04*10^(-38) newton 3) the total resistance is 1.66 ohms 4) the current is 5.4021 amperes 5) the total power is 48.444 watts
Thanks Annand, major gaff; must have been half awake.
