Problem says:

14. [HRW7 28.P.008.] An electron has an initial velocity of (14.0 j + 21.0 k) km/s and a constant acceleration of (3.50 10^12 m/s2) i in a region in which uniform electric and magnetic fields are present. If B = (400 µT) i, find the electric field E.

V/m i + V/m j + V/m k

I know i'm getting the wrong answer because i tried to submit the i component and it was wrong i got:

19.88i

any ideas where i screwed up?
