Answer 1

Answer:

Answer:

The Torque acting is 3/4 N-m

Explanation:

From the definition of torque we know that, Torque is defined as rate of change of angular momentum.

So, the relation between them is,

\longrightarrow\sf \tau =\dfrac{\Delta L}{\Delta T}⟶τ=

ΔT

ΔL

Solving,

\begin{gathered}\longrightarrow\sf \tau=\dfrac{L_{f} - L_{i}}{T_{f}-T_{i}}\\\\\\\\\longrightarrow\sf \tau = \dfrac{8-5}{4-0}\\\\\\\\\longrightarrow\sf \tau = \dfrac{3}{4}\;Nm\end{gathered}

⟶τ=

T

f

−T

i

L

f

−L

i

⟶τ=

4−0

8−5

⟶τ=

4

3

Nm

\begin{gathered}\\\end{gathered}

∴ The Torque acting on the body is 3/4 N-m.
