I Electrical potential, II Torque, III Kinetic Energy, IV Momentum. Which of the quantities listed are vectors?

Answer Details

Vectors are physical quantities that have both magnitude and direction. Scalars, on the other hand, are quantities that have only magnitude and no direction.
Of the four quantities listed, torque and momentum are vectors, while electrical potential and kinetic energy are scalars.
Torque is a measure of the force that causes an object to rotate around an axis or pivot point. It has both magnitude and direction, as it depends on the position and orientation of the object and the direction of the applied force. Momentum is a measure of an object's motion, and it has both magnitude and direction, as it depends on the object's mass and velocity.
Electrical potential is a scalar quantity that represents the amount of energy required to move an electric charge from one point to another in an electric field. It has only magnitude and no direction. Kinetic energy is also a scalar quantity that represents the energy an object possesses due to its motion. It is determined by the mass and speed of the object and has only magnitude.
Therefore, the correct answer is (A) II and IV, as torque and momentum are the only vector quantities listed.
