A massive horizontal platform is moving horizontally with a constant acceleration of \[10m/{{s}^{2}}\]as shown in the figure. A particle P of mass m = 1 kg is kept at rest at the smooth surface as shown in the figure. The particle is hinged at O with the help of a massless rod OP of length 0.9 m. Hinge O is fixed on the platform and the rod can freely rotate about O. Now the particle P is imparted a velocity in the opposite direction of the platform?s acceleration such that it is just able to complete the circular motion about point O. Then the maximum tension appearing in the rod during the motion is 10n. Find the value of n.
