As per the chemistry rule, we all know that mobility of any particle (i.e. speed is inversely proportional to its size) Here B's mobility is more so it must have a less diameter.

p=2piNT/60.
There for torque and speed are inversely proportional. So b diameter is lesser than a.
There for torque and speed are inversely proportional. So b diameter is lesser than a.

Power = Inertia*Angular velocity.
If angular velocity is increased, I would decrease to maintain same power.
If angular velocity is increased, I would decrease to maintain same power.

If diameter of shaft increases means speed will decreases, on other hand, Torque will increases.

Speed of shaft is inversely proportional to its diameter.

Because velocity V = r*omega.
v = D/2*omega.
So v = D/2*2*pi*n.
D*n = v.
Now D is inversely proportional to n. So more R.P.M less diameter.
v = D/2*omega.
So v = D/2*2*pi*n.
D*n = v.
Now D is inversely proportional to n. So more R.P.M less diameter.

Dia is inversely proportional of speed.

Speed of shaft and its diameter both are inversely depends on so, less diameter have more speed.

Is diameter of shaft is directly proportional to speed?
