answer = w = 300

Answer 2

$\huge{\mathcal{\underline{\underline{\pink{Solution:-}}}}}$

Force applied by ravi = 10 N

Displacement = 30 cm = 0.3 m

$\large\rm\bold{\underline{\boxed{W\:=\:F.S}}}$

$\large\rm{W\rightarrow{Work\:done}}$

$\large\rm{F\rightarrow{Force\:applied}}$

$\large\rm{S\rightarrow{Displacement\:due\:to\:application\:of\:Force}}$

Work done by Ravi = 10 × 0.3

⇒ Work done by Ravi = 3 J

∴ Work done by Ravi is 3 J

$\large{\mathcal{\underline{\underline{\green{Additional\:Information:-}}}}}$

❃ Work done when a Force 'F' is applied making an angle θ with the horizontal and Causes a displacement 'S' is given by ,

$\large\rm\bold{\underline{\boxed{W\:=\:F.Scos\theta}}}$

❃ Work done when Power 'P' and time 'T' are given ,

$\large\rm\bold{\underline{\boxed{W\:=\:P\times\:T}}}$

❃ SI unit of Work is Joules (or) N.m . Represented by 'J'

❃ CGS unit of Work is Dyne.cm (or) Ergs . Represented by erg
