A particle has a mass $m$ and an electric charge $q$. The particle is accelerated from rest through a potential difference $V$. What is the particle's de Broglie wavelength, expressed in terms of $m, q,$ and $V ?$
A particle of mass m and charge q has an initial speed v at point A and moves to a point B where the electric potential is V greater than at point A. What is the particle's kinetic energy at point B? .5*m*v^2-q*V .5 * m * v^2 - q * V
Adi S.
A charged particle is accelerated from rest through a potential difference $\Delta V .$ The particle then passes straight through a velocity selector (field magnitudes $E$ and $B$ ). Derive an expression for the charge-to-mass ratio $(q / m)$ of the particle in terms of $\Delta V, E,$ and $B$.
