In a region of uniform electric field of intensity E , an electron of mass m_e is released from rest. The distance travelled by the electron in a time t is
Options
- A2 m_e t^2 e
- Be E t^2 2 m_e
- Cm_e g t^2 e E
- D2 E t^2 e m_e
Correct answer
B. e E t^2 2 m_e
Step-by-step solution
a= F m_e = e E m_e As, S= 1 2 a t^2= 1 2 e E m_e t^2
