Relation between ke and stopping potential
WebApr 8, 2024 · The stopping voltage otherwise called as stopping potential is defined as the voltage difference needed to prevent the electrons from moving between the plates and … WebNov 21, 2024 · From the work-energy theorem, this is equal to the change in kinetic energy d K. However, since the force is conservative, K + U is constant, so d K = − d U , where U is the potential energy. So we have: − d U = F 1 d x + F 2 d y + F 3 d z. From multivariable calculus, we know that d U = ∂ U ∂ x d x + ∂ U ∂ y d y + ∂ U ∂ z d z.
