In a region of uniform electric field ofn intencity E, an electron of mass `m_e` is released from rest. The distance travelled by the eloctron in a time t is

Options

A. `(2m_et^2)/e`
B. `(eEt^2)/(2m_e)`
C. `(m_e""g t"^2)/(eE)`
D. `(2Et^2)/(em_e)`

Explanation

`mu=0.8,mu_k=0.6,g=10 m/(s^2)`(given)
Accelerration,
`a=(mu_s-mu_k)g`
`implies a=(0.8-0.6)xx10`
`:.a=(2m)/(s^2)`
