At t=0, a positively charged particle of mass m is projected from the origin with velocity `u_(0)` at an angle `37^(@)` fromn the x-axis as sown in the figure-4.235. a constant `vecB_(0)=B_(0)hatj` is present in space. After a time internal `t_(0)` velocity of particle may be:

A

`u_(0)[sqrt(39)/(2)i+(3)/(5)hatj-(hatk)/sqrt(3)]`

B

`u_(0)[(hati)/sqrt(3)+(hatj)/sqrt(2)+(hatk)/sqrt(6)]`

C

`u_(0)[sqrt(39)/(10)hati+(3)/(5)hatj+(1)/(4)hatk]`

D

`u_(0)[sqrt(39)/(10)hati+(3)/(5)hatj+(1)/(2)hatk]`
