When a body of weight 'W' is kept suspended by a string, the weight of the body pulls the string downwards, while the string pulls the body upwards with an equal force, this force is called?
Correct answer: C. The tension in the string
- A. The frequency of the string
- B. The displacement of the string
- C. The tension in the string
- D. The wavelength of the string
Explanation
When a body is suspended by a string, the downward gravitational force (weight) is balanced by an upward force called tension. This tension is equal in magnitude to the weight of the body, keeping the system in equilibrium. The incorrect options (frequency, displacement, wavelength) all pertain to aspects of wave motion and vibrations, which are unrelated to the static equilibrium scenario described in the question.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
