Question

a rock weighing 2 newtons was carried 2 meters how much work was done

Answer 1

$\bigstar$ Given

• Force = 2 Newtons
• Displacement = 2 metres

$\bigstar$ To Find

• Work done

$\bigstar$ Solution

We know that

$\red{\rm \longrightarrow W=Fs}$

Here

• W = Work done
• F = Force
• s = Displacement

Units

• W = Joule (J)
• F = Newton (N)
• s = metre (m)

According to the question

We are asked to find the work done

Therefore

We need to find "W"

Given that

• Force = 2 Newtons
• Displacement = 2 metres

Hence

• F = 2 N
• s = 2 m

Substituting the values

We get

$\pink{\rm \longrightarrow W=2 \times 2 \ J}$

Therefore

$\purple{\rm \longrightarrow W=4 \ J}$

Hence

$\checkmark$ Work done = 4 J

Answer 2

Gɪᴠᴇɴ :

• Weight of a rock is 2 N.

$\longmapsto\:\:\bf\blue{Force\:(F)\:=\:2\:N}$

• The rock was carried 2 m.

$\longmapsto\:\:\bf\purple{Displacement\:(s)\:=\:2\:m}$

Tᴏ Fɪɴᴅ :

• Work done.

Cᴀʟᴄᴜʟᴀᴛɪᴏɴ :

$\bf\pink{We\:know\:that,}$

$\red\bigstar\:\:\bf{\green{\underline{\boxed{\bf{\color{peru}Work\:done\:(W)\:=\:F\:.\:s\:}}}}}$

$:\implies\:\:\bf{W\:=\:2\times{2}\:}$

$:\implies\:\:\bf\orange{W\:=\:4\:Joules}$

$\Large\bold\red{Therefore,}$

Work done is 4 J.
