Question

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

Answer 1

Gɪᴠᴇɴ:

• Weight of a rock is 2N.

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

• The rock was carried 2M.

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

TᴏFɪɴᴅ:

• Work done.

Cᴀʟᴄᴜʟᴀᴛɪᴏɴ:

$\begin{gathered}\bf\pink{We\:know\:that,} \\ \end{gathered}$

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

$\begin{gathered}:\implies\:\:\bf{W\:=\:2\times{2}\:} \\ \end{gathered}$

$\begin{gathered}:\implies\:\:\bf\blue{W\:=\:4\:Joules} \\ \\ \end{gathered}$

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

The Work Done is 4 J.

Answer 2

$\huge\mathcal\colorbox{black}{{\color{blue}\huge\ {Aɴsᴡᴇʀ \: }}}$

$\bigstar \sf Given :$

• Force = 2 Newtons
• Displacement = 2 metres

$\bigstar \sf To Find :$

• Work done

$\bigstar \sf Solution :$

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
