1. The problem statement, all variables and given/known data I'm stuck on 3 questions from my assignment as an access student (I never studied science before) First thing is: Explain the term " centre of gravity" and where it is in relation to a metre rule. Second: A metre rule is pivoted at its 10cm mark. A 1N force is suspended from the 30cm mark and a newton meter is used to measure the force required to suspend the ruler horizontally from the 90cm mark. Draw a free body force diagram to represent this. So this is what i did: Its as an attachment 2. Relevant equations First thing is: Explain the term " centre of gravity" and where it is in relation to a metre rule. Is my picture right? and how shall i name those forces? Thanks for your time.
