Is angular velocity a scalar or vector quantity?

• Scalar
• Vector
• Pseudoscalar
• Tensor

Which axis gives the minimum moment of inertia for a rectangular lamina?

• Axis along length
• Axis along breadth
• Axis through edge
• Axis through center perpendicular to plane

What is the effect of doubling the mass on the moment of inertia?

• It quadruples
• It halves
• It doubles
• No effect

Which has a greater moment of inertia: a solid disc or a hollow ring of same mass and radius?

• Solid disc
• Both are equal
• Hollow ring
• Depends on thickness
