Question

Which of the following statements about torque is correct?

Options

• Torque direction is arbitrary

• Torque is a scalar equal to rF

• Torque is always along \[\vec F\]

• Torque is a vector \[\vec τ\] = \[\vec r\] × \[\vec F\]

Answer 1

Torque is a vector \[\vec τ\] = \[\vec r\] × \[\vec F\]

Explanation:

Torque is defined by the cross product of position vector and force, giving magnitude and direction.
