An electron has a speed of 6.0 x 10^5 m/s as it passes point A  on it's way to point B.Its speed at B is 12 x10^5 m/s.What is the potential difference between point A and B and which is at higher potential?

A proton has a speed of 3.50 × 105 m/s when at a point where the potential is +100 V. Later, it’s at a point where the potential is –150 V. What’s its speed at this later point?

A negative ion with a net charge of 4 electron charges and a mass of 9.30 x 10 26 kg is initially traveling in the direction shown in the figure below with an initial speed of 7.00 x 10³ m/s. After traveling across the distance x = 3.00 cm the ion comes to rest instantaneously. What is the electric potential of the final position of the ion relative to the electric potential at the ion's initial positiğn. (The electron's final position is a distance x = 3.00 cm to the right of its initial position. O -14.2 V O It is impossible to determine because the ion will not come to rest. O 14.2 V O -3.56 V O 3.56 V

The work done by an external force to move a charge from point A to point B is 15x10^47. If the charge was started from rest and had a kinetic energy 4.82x10 KJ when it reached point B. What must be the potential difference between A and B? How far apart is point B from point A?

At a distance of 0.40 m from a proton, calculate its electric field strength. At this distance, what is the electric potential?

Point A has an electric potential of 33 V and point B has an electric potential of 173 V.  An electron is released from point A and accelerated by the electric field to point B. (a)  What is the change in the electric potential energy of the electron in joules? (b)  What is the speed of the electron when it reaches point B in meters per second?

A particle with a charge of -3.6 µC and a mass of 4.4 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 58 m/s. The only force acting on the particle is the electric force. What is the potential difference VB - VA between A and B? If VB is greater than VA, then give the answer as a positive number. If VB is less than VA, then give the answer as a negative number. Number i Units
