Ans: C.
The centrifugal tension in belts does not Affect the power transmission.
Has no effect on the Power transmitted".
If T1= Tight side-tension, T2= slack side-tension, v= velocity of drive;.
P= (T1-T2)v.
Centrifugal tension (Tc) acts on both tight and slack sides:
P=[ (T1+Tc) - (T2+Tc) ]v.
P= (T1 - T2) we even after considering Centrifugal tension.

For smaller speeds it can be ignored. but for higher speeds it should be taken;
Without centrifugal tension, P= T1 (1-1/e^μθ)V
Considering centrifugal tension (Tc), P= T1-Tc (1-1/e^μθ)V. therefore power will be decreased. OPTION B is correct.

Considering centrifugal tension (Tc), P= T1-Tc (1-1/e^μθ)V. therefore power will be decreased. OPTION B is correct.

Can you elaborate it?

P=T1[1 - 1/, ^μ*β]V.
Hence power transmission is lesser when Centrifugal force is taken into account.
