What is the electric field strength inside the capacitor and potential energy of a proton at the midpoint of the capacitor in this image?
You’re correct. E = V/d = 300/0.003 = 1E5 V/m
The PE of a proton at the 150 V level, with a charge = 1.602E-19 C, is 150 eV or 150*1.602E-19 J.
Energy stored in a capacitor is related to voltage as follows (assuming the dielectric constant is 1, in the absence of other information): W = (1/2) ε (A/d) V^2 And electric field strength can be calculated from voltage and distance: E = – V/d
Hi, i’m sorry i cant answer this.
but if you are older than 13 and u think ur good at physics please can you help me with this work. its just 3 questions. thanks
