Question

a work of 720J is done when a force of 24N is applied to a body. Determine the displacement produced by that body.​

Answer 1

Given :

➳ Work done by force = 720J

➳ Applied force = 24N

To Find :

➾ Displacement of body.

Concept :

➨ Work is defined as the dot product of applied force and displacement.

➨ It is a scalar quantity.

➨ It has only magnitude.

➨ SI unit : Nm or J

Mathematically,

✭ W = F s

where,

◕ W denotes work done

◕ F denotes applied force

◕ s denotes displacement

Calculation :

⇒ W = F s

⇒ 720 = 24s

⇒ s = 720/24

⇒ s = 30m

Answer 2

$\huge\sf\purple{Steps}$

Work done by a body is given by,

$\underline{\boxed{\sf W = FS}}$

Where,

$\quad$◕ W = Work Done

$\quad$◕ F = Force Applied

$\quad$◕ S = Displacement

Substituting the given values,

➝ $\sf W = FS$

➝ $\sf 720 = 24 \times S$

➝ $\sf \dfrac{720}{24} = S$

➝ $\sf \orange{S = 30 \ m}$
