    Answer:

    T=7.5*10^{-5}

    Explanation:

    From the question we are told that:

    Radius r=2cm

    Work done W=1.5×10^-4 joules

    Generally the equation for Work done is mathematically given by

     W=T.dA

    Therefore

     T=\frac{W}{dr}

     T=\frac{1.5*10^{-4}}{2}

     T=7.5*10^{-5}
