# Shouldn't this be a mechanics problem??

A ring of radius $$R=1m$$ having uniformly distributed charge $$Q=20C$$ is mounted on a rod suspended by two identical strings. The tension in strings in equillibrium is $${T}_{0}=40$$. Now a vertical magnetic field $$B=10T$$ is switched on and the ring is rotated at constant angular velocity $$\omega$$. Find the maximum $$\omega$$ with ehich the ring can be rotated if the strings can withstand a maximum tension of $$\frac { { 3T }_{ 0 } }{ 2 }$$. The distance between the strings is $$D=5m$$
