Question

a forces 8 N is used to drag a chair 2.5 M across a room. Calculate the work done to move the chair

Answer 1

Answer:

Given :-

• A force is 8 N is used to drag a chair 2.5 m across a room.

To Find :-

• What is the work done to move the chair.

Formula Used :-

$\clubsuit$ Work Done Formula :

$\longmapsto \sf\boxed{\bold{\pink{Work\: Done =\: F \times D}}}$

where,

• F = Force
• D = Distance

Solution :-

Given :

$\bigstar$ Force = 8 N

$\bigstar$ Distance = 2.5 m

According to the question by using the formula we get,

$\longrightarrow \sf Work\: Done =\: 8 \times 2.5$

$\longrightarrow \sf Work\: Done =\: 8 \times \dfrac{25}{10}$

$\longrightarrow \sf Work\: Done =\: \dfrac{8}{1} \times \dfrac{25}{10}$

$\longrightarrow \sf Work\: Done =\: \dfrac{8 \times 25}{1 \times 10}$

$\longrightarrow \sf Work\: Done =\: \dfrac{20\cancel{0}}{1\cancel{0}}$

$\longrightarrow \sf Work\: Done =\: \dfrac{20}{1}$

$\longrightarrow \sf\bold{\red{Work\: Done =\: 20\: J}}$

$\therefore$ The work done to move the chair is 20 J .
