A proton enters a region with E = 2.5 × 10³ N/C (vertical) and B = 0.5 T (into the page). If the proton moves undeflected, calculate its velocity and describe its trajectory if the electric field is suddenly turned off.

He’d found the story where forces dance in perfect balance. And on exam day, when he saw Problem 1—a proton in crossed fields—he didn’t panic. He just wrote: “Santillana, página 34, problema 34l. La velocidad es 5000 m/s…”
