Question

~ Physics Question :-


A boy climbs on a pole of height 50 m. In doing so, he does 5000 J of work. Find his mass.
​

Answer 1

Answer:

mass=5000÷50×10=1000kg

Answer 2

$\large{\maltese{\underline{\underline{\pmb{{\pink{\sf{\;Given\; That \;:}}}}}}}}$

$\;$

$\twoheadrightarrow$Heights of Pole (H) = 50m

$\twoheadrightarrow$Work Done by boy (w) = 5000J

$\twoheadrightarrow$Value of (g) = 10

$\;$

$\large{\maltese{\underline{\underline{\pmb{{\green{\sf{\;Need\;To\; Find\;:}}}}}}}}$

$\;$

$\dashrightarrow$We have to calculate Boy mass ?

$\;$

$\large{\maltese{\underline{\underline{\pmb{{\blue{\sf{\;Formula \;Used\; Here\;:}}}}}}}}$

$\;$

$\dashrightarrow$w = mgh

$\;$

$\pink\maltese$Where :

$\;$

• $\leadsto$w = Work done
• $\leadsto$m = Mass
• $\leadsto$g = Acceleration
• $\leadsto$h = Height

$\rule{300}1$

$\;$

$\large{\bigstar{\underline{\underline{\pmb{{\red{\sf{\;Putting \;Values \;in \;Formula\;:}}}}}}}}$

$\;$

$:\longmapsto$ w = mgh

$:\longmapsto$5000J = m × 10 × 50

$:\longmapsto$5000J = 500m

$:\longmapsto$m = 5000 / 500

$:\longmapsto$ $\boxed{\underline{\pink{\mathfrak{m \;=\; 10kg}}}}$

$\;$

$\rule{300}1$

$\;$

$\large{\dag{\underline{\underline{\pmb{{\purple{\sf{\;Therefore \;:}}}}}}}}$

$\;$
