Since we know that q 1 and q 2 have the same magnitude (remember that P is on the perpendicular bisector of our finite line of charge) we can write the relationship that q 2 = -q 1 Since q 1 and q 2 are equal, we can renamed our angle as just q without the need of any further subscripts. Feb 12, 2019 · This temperature may be very different from the true SAT even at that location and has certainly nothing to do with the true regional SAT. To measure the true regional SAT, we would have to use many 50 ft stacks of thermometers distributed evenly over the whole region, an obvious practical impossibility. Q.

Dec 25, 2015 · For the charges to settle on each of the spheres, there should be no flow of charges across these two spheres. This is only possible if the potential difference between the two spheres is ZERO. So, the potential on the surface of each of the two spheres must be equal. Initially, the potential of the bigger sphere at the surface : V i b = k ∗ Q R. Lets say some charges (q) flow from the bigger sphere to the smaller sphere and the potential is equal across the both spheres.
