Question

An electron is released from rest in a region between two parallel plates with electric field E. The plates are delta x = 7.5 cm apart. The final speed of the electron is 5.8 times 10^6 m/s. [e = 1.602 times 10^-19]; mass of electron = 9.1 times 10^-31 kg) A charge of 60 mu C flows through capacitor C2 Calculate the voltage V at the terminas A and B C1 = 12 mu F C2 = 15 mu F C3 = 30 mu F C4 = 24 mu F Two students Jack and Jill are assigned an experiment to test the final values that charges acquire after being touched and separated. The instructions provided are as follows. Step 1: A touch B then separate. Step 2: B touch C then separate. Step 3: C touch D then separate. Jack goes to the lab alone and performs the experiment according to instructions and leaves. Jill comes to the lab later, performs the exact same experiment not realizing that her partner had just completed the experiment. Determine the final value of charge D after this second trial. A = 12 mu C B = -10 mu C C = 8 mu C D = -15 mu C
