Answer:
Angular acceleration of the disk will be 
Explanation:
We have given mass of the disk m = 5 kg
Diameter of the disk d = 30 cm = 0.3 m
So radius 
Moment of inertia of disk is given by 
Force is given by F=4 N
Torque is given as 
We also know that torque is given by 
Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.
<h3>What is the explanation for the above?</h3>
For every interval of odd multiple of π, to next even multiple of π, sinθ will be negative.
Mathematically,
Sin θ will be negative in
[(2n +1)π, (2n + 2)π]
Where, n is any integer (Positive or negative).
Hence, it is right to state that Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.
