1. The problem statement, all variables and given/known data Find the centripetal force required to rotate 6 kg object in a circle at a radius of 6m at one revolution per second. 2. Relevant equations C.F. = mv2/r 3. The attempt at a solution[/b Circumference=2 pi r=2*3.14*6=37.68 C.F. = 6*(37.68)2/6=1419.78 I just want to check whether my working is correct or not.
