Unless you define work done on the system as negative.

comment How is the formula for the capacitance of a parallel plate capacitor derived?
Is this the equation you are refering to? en.wikipedia.org/wiki/Capacitance#Capacitors $$C=\epsilon_r\epsilon_0\frac{A}{d}$$

Hi @satyatch. If you use dollar marks $\$$ around your text, you can make good-looking math and formulas. See here physics.stackexchange.com/editing-help#latex. If you could edit your question to be more clear, it would help me to understand it better.

comment Does an orbiting body accelerate?
@HolgerFiedler A satellite does not accelerate because it is in equilibration and follows a geodesic path, Watch out now, this is not correct and quite confusing in regard to this question. Though the centripetal acceleration might be negligible in a close-up point-of-view, it is there and it is the cause of the circular path/orbit of the satellite.

comment Does an orbiting body accelerate?
@Mark Why shouldn't the joint action of two normal and equal vectors produce an acceleration of course they should, this acceleration is just not at 90 degrees - it is along with $F$

comment Does an orbiting body accelerate?
@Mark, something is unclear in what you ask. There can only be one resultant force vector. And if the acceleration points at 90 degrees then the resultant force will also point at 90 degrees. This is Newton's second law, $F_{res}=ma$

All forces cause acceleration Not quite; the sentence should rather be "The net force causes acceleration".

comment Is it possible to build a thermoelectric nuclear power plant?
@EnergyNumbers Please let me clear out what "it" is in the line that you quote. "it" is the nuclear power plant described in the question. In other words, a nuclear power plant that is being driven by steam through turbines. The question clearly asks if such plants can be driven by the thermoelectric effect instead of steam. There is certainly nothing incorrect in the answer; if I'm mistaken, please elaborate.
