A particle of mass 1 \times 10^{-26} {\kg} and charge 1.6 \times 10^{-19} {\C} travelling with a velocity 1.28 \times 10^6 {\ms}^{-1} along the positive X-axis enters a region in which a uniform electric field \bo {E} and a uniform magnetic field of induction \bo {B} are present. If \bo {E}=-102.4 \times 10^3 \stackrel{\^}{\bo {k}} {\NC}^{-1} and \bo {B}=8 \times 10^{-2} \stackrel{\^}{\bo {j}} {\Wbm}^{-2} the direction of motion of the particles is

Correct Answer is : along the positive X-axis

at 45^{\circ} to the positive X-axis

at 135^{\circ} to the positive X-axis

Marks: +1, -0

A particle of mass 1×10−26‌kg and charge 1.6×10−19C travelling with a velocity 1.28×106ms−1 along the positive X-axis enters a region in which a uniform electric field E and a uniform magnetic field of induction B are present. If E=−102.4×103

NC−1 and B=8×10−2

Wbm−2 the direction of motion of the particles is

along the positive X-axis
along the negative X-axis
at 45∘ to the positive X-axis
at 135∘ to the positive X-axis
