Let l be the moment of inertia of a uniform square plate about an axis AB that passes through its centre and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the centre of the plate and makes an angle θ with AB. The moment of inertia of the plate about the axis CD is then equal to

Inertia is the tendency of an object to resist changes in its state of motion or rest, depending on mass. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

Two point masses of 0.3 kg and 0.7 kg are fixed at the ends of a rod of length 1.4 m and of negligible mass. The rod is set rotating about an axis perpendicular to its length with a uniform angular speed. The point on the rod through which the axis should pass in order that the work required for rotation of the rod is minimum is located at a distance of

Rotation is the circular movement of an object around an axis, where every point in the object moves in a circular path. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
