pick out the only vector quantity in the following list:
pressure, power, total path length, torque
Hi,
Vector quantities are those which have magnitude as well as direction. Among pressure, power, total path length and torque, torque is the vector quantity as its direction is mutually perpendicular to the radius from the axis and the force.
One more thing keep it in mind, dot product of two vectors gives a scalar quantity whereas cross product of two vectors gives a vector quantity.
