A patialy moves along half the circumference of a circle of 1 meter radius. Calculate
the work done if the force at any point inclined at 60o to the tangent at that point has
5 New tones magnitude

  • physics -

    You must mean 5 Newtons, not 5 New tones.

    Force is not measured in tones.

    What is a patialy?

    If the problem that you meant to ask is:

    <<A particle moves along half the circumference of a circle of 1 meter radius. Calculate the work done if the force at any point is inclined at 60 degrees to the tangent at that point, and has 5 Newtons magnitude.>>

    If that is the question, then the answer is the product of the distance that the particle travels (pi meters) and the component of the force along the direction of motion (which is the tangent to the circle)

    Work = pi * 5.0 N * cos60
    = 2.5 pi joules
    = 7.854 J
