Question

4. A proton (charge +e = 1.602x 10^-19 C) moves a distance d = 0.50 m in a straight line between points a and b in a linear accelerator. The electric field is uniform along this line, with magnitude E = 1.5x10^7 N/C in the direction from a to b.

Determine

(a) the work done on the proton by the field;

(b) the potential difference Va - Vb.

Both parts of the question has been answered

A particle with charge 1.60×10−19 C is placed on the
x axis in a region where the electric potential due to
other charges increases in the +x direction but does not
change in the y or z direction.
The particle, initially at rest, is acted upon only by the
electric force and moves from point a to point b
along the x axis, increasing its kinetic energy by
1.44×10−18 J . In what direction and through what
potential difference Vb−Va...

A proton with a charge qp = +e = +1.60 × 10–19 C moves with a
speed v = U × 105 m/s East through the Earth’s magnetic field,
which has a value of B = 55.0 ?T and points northward at a
particular location. What is the strength of the magnetic force F
when the proton moves eastward?

A proton (mass = 1.67x10^27 kg, charge = 1.60x10^19 C) moves
from point A to point B under
the influence of an electrostatic force only. At point A the proton
moves with a speed of 50
km/s. At point B the speed of the proton is 80 km/s. Determine the
potential difference VB-VA.
I know the answer is -20, but I'm not sure how to get
it...thanks!

A proton (electric charge + e, and mass mp) moves in the z +
direction after being accelerated from rest by a potential
difference V. Then the proton passes through a region of space with
a constant electric field E in the x + y direction a constant
magnetic field B in the y + direction. What is the value of | E | /
| B |

a)
A particle (charge = 70 μC) moves in a region where the only
force on it is an electric force. As the particle moves 25 cm from
point A to point B, its kinetic energy increases by 4.2 mJ.
Determine the electric potential difference, VB - VA. (in
Volts)
b)
Points A [at (3, 1) m] and B [at (8, 8) m] are in a region where
the electric field is uniform and given by
E→=(4iˆ+3jˆ)E→=4i^+3j^A- VB? (in Volts)

A particle with charge 3.20×10?19 C is placed on the x axis in a
region where the electric potential due to other charges increases
in the +x direction but does not change in the y or z
direction.
The particle, initially at rest, is acted upon only by the
electric force and moves from point a to point b along the x axis,
