studied so hard for relativity yet only one q in it. and btw for the projectile, if you wrote the same horizontal velocity in ur working but didnt draw it like that do u get a mark or no? it was 4 marks
lol idk if i got the projectile one right. option was alright except for the binding energy one :/ i also didnt know how to do the stopping voltage one like i drew another parallel line next to it and probs calculated the whole frequency wrong
