The space has electromagnetic field which is given as `vecB= -B_(0)hatk` and `vecE=E_(0)hatk`. A charged particle having mass `m` and positive charge `q` is given velocity `v_(0)hati` at origin at `t=0sec`. The `z` coordinate of the particle when it passes through the `z-`axis is (neglect gravity through motion)

A

`(2pi^(2)mE_(0))/(qB_(0)^(2))`

B

`(4pi^(2)mE_(0))/(qB_(0)^(2))`

C

`(mE_(0))/(qB_(0)^(2))`

D

`(-4pi^(2)mE_(0))/(qB_(0)^(2))`
