$\sf \red {\underline{\underline{provided\: that:}}}$

$\bullet \tt {Mass\: of\: the\: body(m)=20kg}$

$\bullet \tt {Pull\: of\: gravity\: on\: mass\: 1kg=10N}$

$\sf \orange {\underline{\underline{We\: know:}}}$

$\tt {\fbox{Force=mass×acceleration}}$

➻Supplanting the given values,

$\colon \to \tt {F=m×a}$

$\colon \to \tt {F=20×10}$

$\colon \to \tt \green {\fbox{Force=200Newtons}}$

$\sf \purple {\underline{\underline{Thereupon,}}}$

➻Weight of the body is "200 Newtons" respectively.
