MFF06 (10 points, 1 part)
At a point in space, P, near a moving charge, q, the magnetic field vector, $\vec{B}$, is given by:
$\vec{B} = (2.5 \mu T) \hat{j} + (-2 \mu T) \hat{k}$
The charge q = +1.5 µC is moving at a speed of v = 2350 m s⁻¹ and the displacement vector $\vec{r}$ that points from q to P is given by:
$\vec{r} = (8.4 \ mm) \hat{i} + (-1.4 \ mm) \hat{j} + (-1.7 \ mm) \hat{k}$
Find the angle φ between the velocity vector $\vec{v}$ and the displacement vector $\vec{r}$ (in rad)
