How do you find stopping potential?
The stopping potential can be found by measuring the maximum kinetic energy of the emitted photoelectrons and then using the equation KE = eV, where KE is the maximum kinetic energy, e is the charge of an electron, and V is the stopping potential. By rearranging the equation, the stopping potential can be calculated as V = KE/e.
What is stopping potential?
The stopping potential is the potential (energy/unit charge) or (Joules/Coulomb) that must be applied to stop the electrons from being ejected from the surface when the light is shone on it.
What metal has the highest negative potential?
The metal with the highest negative potential is Francium. It is located at the bottom of Group 1 in the periodic table, making it the most reactive alkali metal with the most negative standard electrode potential.
What is the stopping potential formula used to calculate the minimum voltage required to stop the emission of electrons in a photoelectric experiment?
The stopping potential formula is V hf/e, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and e is the elementary charge. This formula is used to calculate the minimum voltage needed to stop the emission of electrons in a photoelectric experiment.
What is the relationship between force, negative derivative, and potential energy in a system?
In a system, force is related to the negative derivative of potential energy. This means that the force acting on an object is equal to the negative rate of change of its potential energy.

How do you get a negative potential?
A negative potential can be obtained by positioning a charged object in a region of space where the electric potential due to other charges is lower than the reference point (often considered as ground or zero potential). This can occur, for example, near a negatively charged plate in a capacitor or within the electric field of a negative charge. The potential is defined relative to a chosen reference point, so if the potential at that point is lower, it results in a negative value. Additionally, using a battery with a negative terminal can effectively create a negative potential in a circuit.

During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
