A charged particle of mass m and charge q is released from rest in an uniform electric field E. Neglecting the effect of gravity, the kinetic energy of the charged particle after t seconds is:
- \(\frac{2 \mathrm{E}^{2} \mathrm{t}^{2}}{\mathrm{mq}}\)
- \(\frac{E q^{2} m}{Z t^{2}}\)
- \(\frac{\text { Eqm }}{\text { t }}\)
- \(\frac{E^{2} q^{2} t^{2}}{2 m}\)
Answer
(D) E^ 2 q^ 2 t^ 2 2 m
