• 5 J
• π J
• 5π J
• 10π J

What is the direction of torque vector determined by?

• Left-hand rule
• Clockwise rule
• Right-hand rule
• Gravity

What is the primary factor that determines the moment of inertia of a body?

• Color
• Temperature
• Distribution of mass relative to the axis
• Speed

What is the vector nature of angular displacement for finite rotations?

• It is always a vector
• It is a scalar
• It is not a vector
• It is a tensor

What is the effect of increasing moment of inertia on angular acceleration for a constant torque?

• It increases
• It remains same
• Angular acceleration decreases
• It becomes zero
