Specific Charge AS Level HELP!?!?!! Hi, RIGHT, I am in desperate need of help I am attempting to teach myself Specifiction A AQA AS Physics and need help with how to figure out the specific charge of a nucleus when the charge and mass are not stated. It is hard to explain without diagrams but if a nuclus is given, for example C with a small 12 on top and a small 6 on the bottom how would you work out the specific charge for this because my textbook says that you can only work out specific charge if you have the charge and the mass? Hope this makes a vague amount of sense and I may be being very silly but i need someone to explain this to me at a very basic level!!!
