Hola User________________

Here is Your Answer...!!!

⭐Actually welcome to the concept of the Rotational Dynamics...

⭐Basically we know that ,

⭐Torque on a body is given as .

⭐Tau = I alpha

⭐where I is the moment of inertia and Alpha is the angular acceleration

⭐Now if we see here in the case of the Pulley

⭐Tension is acting as the Force applied here with perpendicular distance of Radius R

⭐so we can write

⭐Torque = F x R

⭐thus tau = T × R ... ( in this case T = F )

⭐thus equating both the equations we get the relation as

⭐T . R = I . alpha

⭐so here the angular acceleration will be given as .

⭐APLHA ( @) = T.R / I
