This question has Statement 1 and Statement 2. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement 1: When moment of inertia of a body rotating about an axis with angular speed increases, its angular momentum is unchanged but the kinetic energy increases if there is no torque applied on it. Statement 2: , kinetic energy of rotation

Options:

Answer:
B
