Question

Im having trouble trying to figure out where to start thisproblem. It seems simple due to it only involving one number. Aproton's speed as it passes point A is5.00×104 m/s. What is the proton's speed at point B? point A=30V point B= -10V Should the proton constant be used? Any other advice ishelpful Im having trouble trying to figure out where to start thisproblem.

Explanation / Answer

      Kinetic Energy of protonatA      KA   =   (1/2)* m * vA2                                                                =   0.5* 1.66 * 10-27 * (5.00 *104)2                                                                =   2.075* 10-18   J    Energy gained byproton   K   =   qp*(VA   -   VB)                                                    =   1.6* 10-19 * {30 - ( - 10)}                                                    =   6.40* 10-18   J    Energy of proton atB      KB   =   KA   +   K                                     (1/2)* m *vB2   =   2.075* 10-18   +   6.40 *10-18          0.5 *1.66 * 10-27 *vB2   =   8.475* 10-18   J    vB   =   (8.475* 10-18 / 8.30 * 10-28)             =   1.01* 105   m/s          0.5 *1.66 * 10-27 *vB2   =   8.475* 10-18   J    vB   =   (8.475* 10-18 / 8.30 * 10-28)             =   1.01* 105   m/s
