To calculate the speed of electrons from an accelerating potential, it is essential to understand that the potential difference (V) provided by an electrical source accelerates the electrons from rest to a certain velocity (v). The force acting on the electrons can be expressed using the equation F = ma, where F is the electric force (Fe = Eq) and q represents the charge of the electron. The work done by the potential difference is given by the equation W = VQ, where Q is the charge of the electron. By equating the work done to the kinetic energy (Ek = 1/2 mv^2), one can derive the relationship between the accelerating potential and the speed of the electrons. This understanding clarifies the concept of accelerating potential in the context of electron motion.
