Statement 1: A uniform thin rod of length L is hinged about one of its end and is free to rotate about the hinge without friction. Neglect the effect of gravity. A force F is applied at a distance x from the hinge on the rod such that force always is perpendicular to the rod. As the value of x is increased from zero to L, the component of reaction by hinge on the rod perpendicular to length of rod increases.
Statement 2: Under the conditions given in statement 1 as x is increased from zero to L, the angular acceleration of rod increases.
Statement 2: Under the conditions given in statement 1 as x is increased from zero to L, the angular acceleration of rod increases.
