Electric Force, Field, and Potential
Why does diffraction occur when matter waves pass through narrow openings?
Gravitational force on particles is altered by passage through a small opening.
Photons collide with the edges of the opening, causing diffraction patterns.
The particulate aspect of matter causes it to channel more forcefully through small spaces.
Due to their intrinsic wavelike characteristics, matter waves simply spread out after passing through narrow openings.
Given that Planck's constant was tripled yet all other quantum mechanical principles held true, what effect could this have on emitted photon energy during electron transitions within atoms?
Photon energies reduce threefold resulting from an inverse proportionate dependency between them & Planck’s Constant.
Photon emissions cease altogether due to certain disruption within integral quantum mechanical operations involving photons themselves.
Photon energy emission will triple reflecting Planck–Einstein relation where triples.
No significant change occurs as photon energies depend primarily upon differences between atomic energy levels.
When calibrating equipment intended to verify conservation of electric charge through electrostatic experiments, what adjustment would most likely reduce systematic error?
Regularly recalibrate voltage sources and measurement devices against known standards.
Use thicker wires throughout the setup to decrease resistance changes over time.
Replace digital voltmeters with analog ones for all measurements taken.
Increase current through devices to generate easily detectable signals.
How might you test if charge conservation holds at extremely small scales by analyzing collisions within a cloud chamber where charged particles leave trails?
Counting trails entering versus exiting without considering particle identities or energy levels.
Observing color changes in trails which indicate different charges based on spectral lines emitted.
Compare incoming particle trail lengths to outgoing paths ensuring total charge remains constant pre- and post-collision.
Measure temperature variations inside the chamber as proof that energy states correspond with charge quantities.
In an electrical circuit, if no energy is added or removed, what can we say about the total amount of electric charge in that circuit?
It stabilizes over time due to capacitance.
It decreases when passing through each component.
It changes depending on resistance levels.
It is conserved.
Which unit represents electrical resistance?
Watt
Joule
Ohm
Volt
If two charged objects with charges +4C and -6C come into contact, what will be the total charge after they separate?
-6C
+4C
-2C
+10C

If the elementary charge (e) were to double in value while all other fundamental constants remained unchanged, how would the electric field strength around a point charge change?
It would double because electric field strength is directly proportional to the charge.
It would halve because doubling the charge causes an inverse effect on the electric field strength.
It would remain unchanged because electric field strength is independent of the magnitude of the charge.
It would quadruple because electric field strength is proportional to the square of the charge.
In which situation will there be no change in the total amount of electric charge within an isolated system?
Lightning transfers electrons from clouds to Earth during a thunderstorm.
An uncharged pith ball acquires some electrons after being rubbed with wool.
An alpha particle composed of two protons and two neutrons is emitted from an unstable nucleus in radioactive decay.
A copper wire transfers electrons from one end to another due to potential difference applied across it.
What experimental setup would most accurately determine whether electric charge is conserved when charging two identical capacitors connected in parallel versus series?
Monitor voltage drop across each capacitor over time believing constant rates signify equivalent total storage capacity.
Record time taken for light bulbs wired in parallel/series with capacitors to dim equally assuming equal power usage equals equal charging.
Measure accumulated stored energy via discharged work done lifting a small mass after fully charging both configurations.
Compare brightness levels of LEDs connected across each set hypothesizing same luminosity implies same amount stored charges
