Question

A charge q moves with a velocity 2 m s-1 along x-axis in a uniform magnetic field vecB =( hati + 2 hatj + 3 hatk) T then charge will experience a force (A) in z-y plane (B) along -y axis (C) along +z axis (D) along -z axis

vecF = q( vecv × vecB) q[(2 hati × ( hati + 2 hatj + 3 hatk)] = (4q) hatk - (6q) hatj

Q. A charge q moves with a velocity $2 m s^{- 1}$ along $x$ -axis in a uniform magnetic field $B = (\hat{i} + 2 \hat{j} + 3 \hat{k}) T$ then charge will experience a force

in $z - y$ plane

along $- y$ axis

along $+ z$ axis

along $- z$ axis

$F = q (v \times B)$
$q [(2 \hat{i} \times (\hat{i} + 2 \hat{j} + 3 \hat{k})] = (4 q) \hat{k} - (6 q) \hat{j}$

Q. A charge q moves with a velocity 2ms−1 along x-axis in a uniform magnetic field B=(i^+2j^​+3k^)T then charge will experience a force

in z−y plane

along −y axis

along +z axis

along −z axis
