Heres a torque problem that has baffled me.(adsbygoogle = window.adsbygoogle || []).push({});

Soon-Yi is building a mobile to hang over her baby's crib. She hangs a .020-kg toy sailboat .010 m from the left end and a .015-kg toy truck .20 m from the right end of a bar .50 m long. If the lever arm itself has negligible mass, where must the support string be placed so that arm balances?

I some how got the radical answer

.077 meters

I just got it out of messing around in Mathematics. Someone help solve this please.

EDIT MESSAGE: I just got .4 meters as my answer. This time i wasn't so careless on my Mathematical work. Please check both my answers.

ALSO,, im using the acceleration due to gravity as 10 m/s^2
