Acceleration of a charge in magnetic field is given
\( \mathrm{P} \) by \( \vec{a}=\frac{q}{m}(\vec{v} \times \vec{B}) \). If a charged particle is projected

W - in a magnetic field \( (2 \hat{i}+2 \hat{j}+2 \hat{k}) \) tesla, then -acceleration of the particle at an instant is \( -(x \hat{i}+2 \hat{j}-6 \hat{k}) \mathrm{m} / \mathrm{s}^{2} \). Value of \( x \) is -
(1) 4
(2) 2
(3) 3
