What is the final velocity of the proton in the previous problem? (The mass of the proton is 1.67 × 10–27 kg.) A. 8 × 1014 m/s B. 1,000 m/s C. 3 × 108 m/s D. 3 × 105 m/s
Homework Answers
A)
Kinetic energy= q*v
=e*500V
=500 eV
Ans: B
B)
Kinetic energy=500 eV
=500*1.6*10^-19 J
= 8*10^-17 J
Kinetic energy is also given as 0.5 *m*v^2
so,
0.5 *m*v^2 = 8*10^-17
0.5*(1.67*10^-27)*v^2=8*10^-17 J
v^2=9*10^10
v=3*10^5 m/s
Ans: D
