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.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
