A proton moves through a uniform magnetic field givenby  B→=(5.52i^−10.0j^+20.9k^) mT. At timet1, the proton has a velocity given by  v→=vxi^+vyj^+(2.19â¢â€‰â€‰km/s)k^ and the magnetic force on the protonis   F→B=(3.69×10−17â¢â€‰N)i^+(2.03×10−17â¢â€‰N)j^ . (a)At that instant, what is vx?(b) At that instant, what isvy?
(a) _ m/s
(b) _ m/s
