Answer:
A. 4d
Explanation:
Magnetic field strength is inversely proportional to distance. So in order to have a smaller magnetic field, we need to move further out from the wire. How far we go exactly can be determined from the formula: B=(μ₀I)/(2πr)
(That is derived from Ampere's Law, which states ∫B•dl=μ₀I)
With that you can set up a ratio between the magnetic fields in both cases. Because the current is the same for both instances, everything reduces out on one side of the equation and leaves you with something that relates the two distances by a ratio of each magnetic field value.

Answer:
Part A:
T=0.096 N m
Part B:
t=11.525≅11.53 seconds
Explanation:
Part A:
In order to find the torque we will use the following formula:
Where T is the torue
r is the radius of bowel
F is the force
r=0.06 m
T=0.096 N m
Part B:
In order to find how long would it take for potter wheel to sto we will proceed the following way:
T=I*α
Where:
T is the Torque
I is the moment of inertia
α is the angular acceleration
α=T/I
we will take T from art A
α=0.096/0.11
α=0.872
α=ω/t
where:
α is the angular accceleration
ω is angular velocity in rad/s
ω=1.6*2ππ
ω=10.05 rad/s
t=ω/α
t=11.525≅11.53 seconds
It will take 11.53 sec for wheel to stop
