A uniform magnetic field of $0.20\ \text{T}$ fills the region to the right of a straight boundary and points out of the page, as in the figure. A proton moving at $2.0 \times 10^{6}\ \text{m/s}$ crosses the boundary into the field, at $30^\circ$ to the normal, tilted towards the top of the page. Take the proton's mass as $1.67 \times 10^{-27}\ \text{kg}$ and its charge as $1.6 \times 10^{-19}\ \text{C}$. Which of the following statements are correct?

Fig. 1: A vertical straight boundary. To its right, a grid of dots shows a uniform magnetic field of 0.20 T out of the page; to its left there is no field. A proton reaches the boundary from the left with a speed of 2.0 x 10^6 m/s, its velocity at 30 degrees to the dashed normal, tilted towards the top of the page.
