Aphototube has a stopping potential of 1v. calculate the maximum velocity of the photoelectron.

The potential at which this occurs is called the stopping potential. ... of the incident light had no effect on the maximum kinetic energy of the photoelectrons. When charge (e) is given in elementary charges, the energy will be calculated in electron volts. ... Motion · Distance & Displacement · Speed & Velocity · Acceleration ...

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
