:( no body help me with me question though

ok second chance I was wrong about a) I can say now that all of them contribute to field at P because The electric fiedl in the expression for Gauss´s law refers to the total electric field, not just the electric field due to any enclosed charge. about question b) the charge enclosed in...

Homework Statement in the following figure, the dashed line denotes a Gaussian surface enclosing part of a distribution of four positive charges. a) which charges contribute to the electric field at P? b) is the value of the flux though the surface, calculated using only the...

it would make any sense to ask P3?

lets call i the total current in the circuit therefore the current that goes through R1. applying kirchhoff's law to the junction where R2 and R3 splits i=i1+i2 the total current is the sum of the current that goes through R2 and R3 so we have: i=i1+i2 i=V/R2 + V/R3 i=(R3+R2)V/R2*R3 but R2=2R3...

Homework Statement three resistors R1=R2 and R2=2R3, are connected to a battery, as show in the figure, if the power dissipated for each one is p1,p2 and p3 respectirvely;p3 must be equal to: Homework Equations P=VI P=V^2/R P=I^2*R The Attempt at a Solution I have tried to...
