number 3 the question with the particles

https://www.webassign.net/C uestion part onny changes iT you suomit or change un nswer ssignment Scoring our last submission is used for your score. What is the total charge of all the electrons in 4.0 kg of H20? Particles of charge Q1-+64 ?C, Q2-+51 ?? and 03 -80 HC are placed in a line (Fig. 16-49). The center one is 0.35 m from each of the others. Figure 16-49 Calculate the net force on each charge due to the other two. (State both magnitude and direction.) An electron with speed vo = 1.4x 106 m/s is traveling parallel to an electric field of magnitude E = 80% 103 N/C (a) How far will the electron travel before it stops?

Explanation / Answer

here,

3)

Q1 = 64 uC = 64 * 10^-6 C

Q2 = 51 uC = 51 * 10^-6 C

Q3 = - 80 uC = - 80 * 10^-6 C

the net force on Q1 , F1 = K * Q1 * Q3 /0.7^2 - K * Q1 * Q2 /0.35^2 N

F1 = 9 * 10^9 * 64 * 10^-6 * 10^-6 * (80/0.7^2 - 51/0.35^2) N

F1 = - 145.8 N

the net force on Q1 is 145.8 N to the left  

the net force on Q2 , F2 = K * Q2 * Q3 /0.35^2 + K * Q2 * Q1 /0.35^2 N

F2 = 9 * 10^9 * 51 * 10^-6 * 10^-6 * (64/0.35^2 + 80/0.35^2) N

F2 = 539.6 N

the net force on Q2 is 539.6 N to the right

the net force on Q3 , F3 = - K * Q1 * Q3 /0.7^2 - K * Q1 * Q2 /0.35^2 N

F3 = - 9 * 10^9 * 80 * 10^-6 * 10^-6 * (64/0.7^2 + 51/0.35^2) N

F3 = - 675.9 N

the net force on Q3 is 675.9 N to the left
