Hi can someone please show me how to do this question, Ive been trying to do it for hours. I’ve got to be missing something.
There is a 100g mass sitting on the 10cm mark, and a 50gmass sitting on the 60cm mark. Force acts at the 30cm mark. I’m told that the centre of mass is at the 50cm mark and I need to find force F
But we haven't even met!
