Answer 2

$\frak{Given}\:\begin{cases} \:\quad\sf Acceleration \:of\:a\:body\:,\:a\:=\:\pmb{\frak{5\:m/s^2\:}}\:\\ \:\quad\sf Force \:Exerted\:on\:a\:body\:,\:F\:=\:\pmb{\frak{\:4\times 10^5\: dynes\:}}\:\end{cases}$

Need To Find : The mass of a body ?

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

We're Provided with the , Acceleration (a) , and Force Exerted (F) on a body and , we'll find Mass (m) of the object using the relation between Force , Mass & Acceleration and, that is : $\underline {\pmb{\sf \: F\:=\:m\:\times \:a \:}}$

$\\ \twoheadrightarrow \sf F \:=\:m\:\times \:a\:\\\\\\ \twoheadrightarrow \sf 4 \:\times 10^5 \:=\:m\:\times \:5\:\\\\\\\twoheadrightarrow \sf 4 \:=\:m\:\times \:5\:\:\qquad \Bigg\lgroup \:1 \:N\:=\:1\:\times 10^5\:dynes\:\Bigg\rgroup\\\\\\ \twoheadrightarrow \sf 4 \: \:=\:m\:\times \:5\:\\\\\\ \twoheadrightarrow \sf 5m\:=\:4\:\\\\\\\twoheadrightarrow \sf m \:=\:\cancel{\dfrac{4}{5}}\\\\\\ \twoheadrightarrow \pmb {\underline {\boxed {\purple {\:\frak{ \:m\:\:=\:0.8\:kg\:}}}}}\:\bigstar \:$

$\therefore \:\underline {\sf \: Hence,\:Mass\:of\:a\:body\:is\:\pmb{\sf 0.8\:kg\:}\:.}\:$
