What should be the electric field acting on a proton so that it remains stationary?
To keep the proton stationary, ori at constant velocity, no field should be present at all. Any nonzero electric field strength will apply a force to a proton according to F=e*E, e being the electric charge quantum and E the electric field strength, thereby changing it’s speed continuously.
Do protons have an electric field?
The concept of an electric field is used to explain why charged particles exert forces on each other. When an electron moves into the electric field of a proton it is pulled to the proton. The electric field gets stronger as we approach the particle.
When a proton and an electron are placed in a uniform electric field both will experience forces of?
equal
Therefore, the magnitudes of the forces on the proton and the electron are equal. Therefore, the correct option is B) The magnitude of the electric forces will be equal.
What is the acceleration of a proton?
Use 1.67×10-27 kg for the mass of a proton, 1.60*10-19 ( for the magnitude of the charge on an electron, and 9.81 m/sť for the magnitude of the acceleration due to gravity. To find the magnitude of the required electric field, we just solve. for. Ei.
What is the acceleration of a proton with a negative electric field?
Solution (a) Choose the x-axis to the right, in the direction of the proton, so that the electric field is negative to the left. If the Coulomb force on the proton is the only important one, the acceleration is xa = e(!E)=m.
What is the electric field strength between two charged parallel plates?
The electric field strength between two charged parallel plates is given by the equation: d V E Gwhere E G= field strength ( C N or m V ) V = potential difference across plates (Volts) d = distance between plates (m) Note: This formula can only be used for electric fields that are uniform or between parallel plates.
What would push a positively charged particle away from an object?
We know that if you have a single positively charged particle, a positively charged particle will be pushed away from it by the electric force. The electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary positively charged particle if there was one there.
What is the electric field due to a uniformly charged sphere?
The electric field due to a uniformly charged sphere is like the field of a point charge for points outside the sphere, i.e., E (r) » 1=r 2 for r ! R. Thus, at 10 cm from the surface, r =15 cm and E (15 cm) =(5=15)
