I think it’s the magnetic field
It is harder to push a box with groceries in it because the mass is weighing the box down. Which makes it harder to push
No cluuuueee :/ sowwwwyyy but good luck
Answer:
The frictional torque is 
Explanation:
From the question we are told that
The mass attached to one end the string is 
The mass attached to the other end of the string is 
The radius of the disk is 
At equilibrium the tension on the string due to the first mass is mathematically represented as

substituting values


At equilibrium the tension on the string due to the mass is mathematically represented as



The frictional torque that must be exerted is mathematically represented as

substituting values
