A body of mass 10 kg is attached to a wire 30 cm long. Area of cross section of the wire is 10 raise to power -6 metre square. It's breaking stress is 4.8×10 raise to power 7 N/metre square. Find maximum angular velocity with which it can be rotated in the horizontal circle?

Answer 1

force=w*length wire
breaking stress*Areawire=w*lengthwire
solve for w
