0.5m 5,000 N/C 5) A proton starts from rest in an E-Field with a strength of 5,000 N/C. After the proton travels the length of the field, 0.5m, it collides inelastically (did someone say momentum?!?!?!) with another helium nucleus (2 protons, 2 neutron (mass neutron is same as a proton for this problem, but a little different in real life)) which is initially at rest. What is the velocity of the proton and Helium nucleus after the collision (Isn’t momentum always conserved during a collision?)? 138,400 m/s (PS: A REAL E-FIELD WOULD NOT START AND END SO ABRUPTLY) 6) A proton enters an E-Field traveling at 20% the speed of light. The E-Field is created by two very very long parallel metal plates that are 3x10 -4 meters apart. The plates create a field with strength 500 N/C. How far will the proton travel before hitting a metal plate? Assume proton enters field perpendicular to the field. See picture… 5.75m (HINT: Projectile Motion… acceleration in the y is NOT -9.8m/s 2 but you can solve for it…..) 7) The plate on the left creates a field that applies a force on charge q. The angle between the plate and the string is 30°. The hanging (as in not moving…. so sum of the forces is….. the FBD for this should have 3 arrows) sphere has a mass of 0.03kg and a charge of 6.4x10 -5 C. What is the magnitude of the Electric Field created by the plate? 2,652.2 N/C 5) A proton starts from rest in an E-Field with a strength of 5,000 N/C. After the proton travels the length of the field, 0.5m, it collides inelastically (did someone say momentum?!?!?!) with

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
