Which of the following correctly describes albert einstein’s interpretation of the photoelectric effect.
the maximum photoelectron energy is equal to the energy of the incident photon plus the minimum energy required to remove the electron from the metal.

the photoelectron energy is equal to the energy of the incident photon.

the maximum photoelectron energy is equal to the difference between the energy of the incident photon and the minimum energy required to remove the electron from the metal.

the maximum photoelectron energy is always more than the energy of the incident photon.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
