Question
My questions are listed below, the questions are underlined and my attempted answers are in bold italics, sorry about the pictures (diagrams) being upside down. I am quite unsure whether these are right if someone could help me that would be great
It would remain the same as neither electrons can leap through air from one object to another
2. I have two metal balls, A and B, each suspended from a length of fishing line. Both balls have been negatively charged, but ball B has twice the total charge of ball A. When the balls are brought near each other they can be seen to repel each other. How does the force exerted on ball A by ball B compare to that exerted by ball B on ball A? i.e. is it the same, greater, lesser? Explain your answer.
Fab=-Fba, so equal in magnitude but opposite in direction
3. Draw the electric potential lines (dashed lines) and electric field lines (solid, with arrows) for a parallel plate capacitor; draw at least five of each to make sure you communicate the details of the shape of the potential and the field.
4.Draw a cicuit diagram of a 6V battery connected across a 10 k? resistor and 1 mF capacitor, in series
a)When you first connect the battery to the components, what is the potential difference across the resistor?
I=V/R, I=6/10,000,I=0.0006A=0.6mA. Then Voltage across resistor, alphaV=IxR, alphaV=0.0006Ax10,000=6V, answer=6V
b)Once current has stopped flowing through the circuit, what is the potential difference across the resistor? Explain your answer.
Potential difference is equal to zero as current equals zero, as alphaV=IxR, when I=0, alphav=0
Explanation / Answer
All your answers are wright
when two charged bodies brought near electron only re allocate themselves in the body creating -ve,+ve poles no net charge and forces are equal and opposite
in last questian entire voltage is getting dropped across capacitor hence no current and no voltage across resistor
