How do I know when to use r2 vs r (unsquared when using the
equations below)?
Are there any keywords to keep in mind? (ie: force: use r2
potential/voltage: use r?)
F = k |q1q2| /r2
vs
V = kQ / r

help please, i dont know how to do it
Charging A 1000uF capacitor was charged using a battery of Vo = 10V via two resistors Ry = 47kN and R2 = 27k1. The simulation was run for a total time duration of 300s. Fig 1(a) shows the charging circuit used for the simulation, Fig 1() shows the Voltage vs. time (V-t) response of the circuit charging via Rę = 47kN and Fig 1(c) shows the (V-1) response of the circuit...

I need to know how I would use only one additional measurement
to find R2, not knowing either resistor's resistance. (I am allowed
to use an oscilloscope)
3. Construct the circuit at the right. Set the output of the DC power supply to 6 volts. (Set using the DMM) Determine the resistance of R2 by a SINGLE additional voltage measurement. Do not make the measurement using the DMM as an Ohmmeter or an Ammeter! [Setup Excludes wiring to meter] SHOW...

Can I know how to do part(c)? I know how to do
(a)(b).
By (a) and (b), I get this 4 results.
1. ▾.F = 2xz5-2xz+3xz2
2. ▾xF = (2xy) i + (5x2z4-z3) j
-(2yz) k
3. ▾.(▾xF) = 0
4. ▾x(▾f) = 0
Next, i need to calculate part (c).
I want the solution of part(c), so don't give me the result of
part(a) and (b) again,
thanks!
