A particle is moving with uniform speed along the circumference of a circle of radius R under the action of a central fictitious force F which is inversely proportional to R3. Its time period of revolution will be given by :
$T \propto {R^{{4 \over 3}}}$
$T \propto {R^{{5 \over 2}}}$
$T \propto {R^{{3 \over 2}}}$
$T \propto {R^2}$
