Explanation:
⇝Given :-
➵ A torque of 20Nm is applied on a wheel initially at rest.
▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃
⇝To Find :-
➵ Find the angular momentum of wheel after 3 seconds.
▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃
⇝Solution :-
❒ We know that :
{\large{\red{\bigstar \: \: {\orange{\underbrace{\underline{\blue{\bf{T = \frac{dL}{dt} }}}}}}}}}★
T=
dt
dL
✏ Here :
➳ T = Torque = 20Nm
➳ dL = Change in angular momentum = ?
➳ dt = Time = 3 seconds
❒ Change in angular momentum :
{\large{\longmapsto{\bf{T = \frac{dL}{dt} }}}}⟼T=
dt
dL
{\large{\longmapsto{\bf{20 = \frac{dL}{3} }}}}⟼20=
3
dL
{\large{\longmapsto{\bf{ {dL} = 20 \times 3}}}}⟼dL=20×3
{\large{\green{:{\longmapsto{\red{\overline{\underline{\boxed{\bf{dL = 60 \: N \: m/s}}}}}}}}}}:⟼
dL=60Nm/s
❒ Hence :
➤ Change in angular momentum is 60 N m/s.
