Question

The force of 150 n is acting on an object the object is displaced through a distance of 500 m in the distance of the force find the work done

Answer 1

Answer

• Work done is 75 kilo-Joules

Given

• The force of 150 N is acting on an object .The object is displaced through a distance of 500 m in the direction of the force

To Find

• Work done

Concept Used

• Work done is defined as the product of force and displacement

• It is dot product

• It is a scalar quantity

$\bullet \;\;\; \bf Work=Force.Displacement$

• SI unit of work is Joule or N-m

Solution

Force acting , F = 150 N

Displacement , s = 500 m

Work done , W = ? N-m

Apply Formula .

⇒ Work done = Force . Displacement

⇒ W = F . s

⇒ W = 150 . 500

⇒ W = 75,000 N-m

⇒ W = 75,000 J

⇒ W = 75 k-J
