  • Work Done by a Force: Physics Problem & Solution
    Given:

    - Displacement, \(d = 2\text{ m}\)

    - Force, \(F = 20\text{ N}\)

    To find:

    - Work done, \(W\)

    Solution:

    The work done on the TV set is given by:

    $$W = Fd\cos\theta$$

    Where \(\theta\) is the angle between the force and displacement vectors. In this case, since the force and displacement are in the same direction, \(\theta = 0\degree\). Therefore, \(\cos\theta = 1\).

    Substituting the given values, we get:

    $$W = (20\text{ N})(2\text{ m})(1) = \boxed{40\text{ J}}$$

    Therefore, the work done on the TV set is 40 J.
