Additional comment: it is an interesting probem because it makes concrete the nexus between 'potential' of physics and 'voltage' of electrical engineering.

Yeah, there are a few different ways you could think about it. Either a closed loop to infinity and back, in which case you can treat the potential as the potential difference between the sphere and infinity: ##\frac{kQ_A}{r} - L\frac{di}{dt} - \frac{kQ_B}{r}##. Or you could think about it in the sense of two potentials ##\frac{kQ_A}{r}## and ##\frac{kQ_B}{r}## and a potential difference between them...
Can blur the lines a little but but usually the distinction is that to discuss potential we have a fixed reference, so it means being extra careful when discussing the potential relative to another arbitrary point (really differences) as opposed to a potential relative to the fixed reference.

Guys I have a lot of these kinda problems just follow me and stay tuned so that we have more of these discussions.
The most recent one i have put up goes by the title- 'Hard Momentum Conservation'
See u there:)

We badly need some humor on this site. We all love physics but we need to take even it a bit more lightly now and then. Thank you! (Of course this song always reminds me of 'Dr. Strangelove' too.)

We helpers love to help! Really! Forces us to review also, often; so in a sense you're a helper too! And all of us love physics all the time!Ayesha02 said:

Especially now that cabin fever has fully set in
