A uniform magnetic field fills a region wide between two parallel boundaries; the field is perpendicular to the page. A charged particle enters perpendicular to the left boundary and moves on a circle of radius in the field (ignore gravity), leaving through the right boundary. The angle through which its velocity has turned when it leaves is ( ).Submit your answer to see whether it is right and the explanation here.
