Q1

A stone of mass \(1\mathrm{kg}\) is tied to end of a massless string of length \(1\mathrm{m}\). If the breaking tension of the string is \(400\mathrm{N}\), then maximum linear velocity, the stone can have without breaking the string, while rotating in horizontal plane, is:

a

\(20{\mathrm{ms}}^{-1}\)

b

\(40{\mathrm{ms}}^{-1}\)

c

\(400{\mathrm{ms}}^{-1}\)

d

\(10{\mathrm{ms}}^{-1}\)
