Please show work for each question so I know how todoit. A charge of +2C is at the origin. When a charge Q is placed at2malong the positive axis, the electric field at 2m along thenegativex axis becomes zero. What is the valueofQ? a.-3C b.-6C c. - 7C d. -8C
8. Electrons in a particle beam each have a kinetic energyof3.2x10-17 J. What is the magnitude of the electric field thatwillstop these electrons in a distance of 0.1m?
a. 200 N/C b.1000N/C c. 2000N/C d. 4000N/C
9. A proton (+1.6x10^-19 C) moves 10cm along the direction ofanelectric field os strength 3.0 N/C. The electricalpotentialdifference between the protonâs initial and endingpointis:
a. 4.8x 10^-19 V b.0.30V c.0.033V d. 30V
10. If an electron is accelerated from rest through apotentialdifference of 1200V, find its approximate velocity at theend ofthis process. ( e= 1.6x10^-19 C, m= 9.1x10^-31kg)
a.1,0x10^7m/s b.1.4x10^7m/s c.2.1 x10^7m/s d.2.5x10^7m/s
