Mass of object is 50g moves in a circular path of radius 10cm find work done

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
