Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge -2.45 μC of mass 5.50 g is initially located 3.00 cm from each of these charges (the figure(Figure 1)) and released from rest. You observe that the initial acceleration of -2.45 μC is 354 m/s2 upward, parallel to the line connecting the two point charges. Find q1 and q2.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
