A particle of charge q(0) and of mass m(...

A particle of charge `q_(0)` and of mass `m_(0)` is projected along the `y`-axis at `t=0` from origin with a velocity `V_(0)`. If a uniform electric field `E_(0)` also exist along the `x`-axis, then the time at which debroglie wavelength of the particle becomes half of the initial value is:

A

`(m_(0)v_(0))/(q_(0)E_(0)`

B

`2(m-(0)v_(0))/(q_(0)E_(0)`

C

`sqrt(3)(m_(0)v_(0))/(q_(0)E_(0))`

D

`3(m_(0)v_(0))/(q_(0)E_(0)))`
