An object of mass "m" is whirled with increasing speed in a horizontal circle. if the string breaks with v0 determine the tension in the string just before the string breaks using the terms m,r(radius of circle), v0, and g.
first think about why does the string breake?
then try to answer when does the string breake
think about the centripetal force and the tension just before the string breaks
try to do something with these two
