Parallel Plates and Potential Difference

Click For Summary
SUMMARY

The discussion focuses on the motion of a proton released from a positive plate in a parallel plate capacitor setup, where the plates are separated by 1.5 cm and maintained at a potential difference of 1200 V. The potential energy of the proton is calculated using the formula Vq, where V is the potential difference and q is the charge of the proton (1.602 x 10-19 C). The kinetic energy gained by the proton upon reaching the negative plate is equivalent to the initial potential energy, allowing for the calculation of its final speed using energy conservation principles.

PREREQUISITES
  • Understanding of electric potential and potential difference
  • Knowledge of kinetic energy and its relation to potential energy
  • Familiarity with the charge of a proton (1.602 x 10-19 C)
  • Basic principles of motion in electric fields
NEXT STEPS
  • Calculate the final speed of the proton using the kinetic energy formula: KE = 0.5mv2
  • Explore the concept of electric fields between parallel plates
  • Study the relationship between potential difference and electric field strength
  • Investigate the effects of varying the distance between the plates on the proton's speed
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of charged particles in electric fields.

Two parallel metal plates are separated by 1.5 cm and are maintained at a potential difference of 1200 V. A proton, initially at rest, is released from the poisitive plate. When it reaches the negative plate its speed is :

So i know that potential energy is Vq.
So i went 1200 V x 1.602 x 10-19, but I have no idea where to go from there.

Thanks!
