Physics 2005 JAMB Past Questions - Question 33: The pair of physical quantities consisting of vectors only are

Correct Answer

B

Explanation

A pair of physical quantities consisting of vectors only are:

1. **Displacement and Force**: Both displacement and force are vector quantities. Displacement is the change in position of an object, and force is a vector that describes the interaction between two objects.

2. **Velocity and Acceleration**: Velocity is a vector quantity that describes the rate of change of displacement, and acceleration is a vector that describes the rate of change of velocity.

3. **Momentum and Impulse**: Momentum is the product of an object's mass and velocity, and it is a vector quantity. Impulse is the change in momentum of an object and is also a vector.

4. **Electric Field and Magnetic Field**: In the context of electromagnetism, both the electric field and magnetic field are vector quantities. The electric field describes the force experienced by a charged particle, and the magnetic field describes the force experienced by a moving charged particle.

5. **Gravitational Force and Torque**: Gravitational force is a vector quantity that describes the attraction between two masses, and torque is a vector that describes the rotational force applied to an object.

These are just a few examples of pairs of physical quantities that consist of vectors. In physics, vectors are used to describe quantities that have both magnitude and direction, and many physical phenomena can be described in terms of vector quantities.
