    Work done = 0.3142 Nm

    Explanation:

    Mass of Object is 50 g

    Circular path of radius is 10 cm ⇒ 0.1 m

    Work done = Force * Distance = ?

    *Distance moved (circular path) ⇒ Circumference of the circular path

    2πr = 2 * 3.142 * 0.1 ⇒ 0.6284 m

    *Force that is enough to move a 50 g must be equal or more than its weight.

    therefore convert 50 grams to newton = 0.5 N

    Recall that; work done is force times distance

    ∴ 0.5 N * 0.6284 m

    Work done = 0.3142 Nm
