A particle has a mass of and a charge of C. The particle is moving at a speed of 452 m/s perpendicularly to the uniform electric field when it enters the field, as shown in the diagram. The particle moves 8.62 mm in the direction of the field before it exits it. What is the strength of the electric field?
A positively charged particle with a charge of 2.45 µC and a mass of kg moves perpendicularly to a uniform electric field, as shown in the diagram. Find the speed of the particle at the point where it leaves the field. Answer to two significant figures.
A particle with a charge of 1.02 µC has a kinetic energy of 0.422 µJ when it enters a region of a uniform electric field. The particle enters the field from below, as shown in the diagram. A short time later, the particle exits the top of the electric field, having meanwhile traveled 115 cm in the direction of the field.
What is the kinetic energy of the particle when it leaves the electric field?
When the particle exits the electric field, is the angle between the particle’s direction of motion and the direction of the field greater than, less than, or equal to the angle between the particle’s direction of motion when it enters the field and the direction of the field?
