7. The figure shows a book-like object rotating around a perpendicular rotation axis through the given point along the center line that is drawn in dashes. The mass is 2.00 kg. The dimensions are a = 0.010 m, b = 0.020 m, and c = 0.0040 m. What is the rotational inertia (kg-m²)? The rotational inertia about a perpendicular axis through the center of mass is given by I =(a² + b²). (A) (B) (C)(D) (E)
