Homework Statement
hi i was doing a practice physics junior olympiad paper when i got stuck in question 11 in this link
[/B]
https://www.scribd.com/document/244111815/SJPO-2013-Special-Round-pdf
Edit by moderator: Inserted relevant extract of the PDF so that helpers do not have to go off-site, download a PDF, and search through it for the problem statement. By the way, it was problem 10, not problem 11
what exactly does the question mean by grazing past the sphere does it mean the proton stops moving or does it continue moving and is the approach for the problem conservation of energy or some other approach.
i know a calculus based approach will work but this competition does not require the use of calculus so please don't give me a calculus approach. and how exactly does the variable l affect the trajectory of the particle i am confused please help? any help will be appreciated thanks!
