When the speed of belt increases,

Answer & Solution
Correct Answer: Option D
When the speed of the belt increases

The power transmitted by a belt drive is directly proportional to the product of the belt tension and the belt speed

Power (P) = (T₁ - T₂) × v, where T₁ is the tension in the tight side, T₂ is the tension in the slack side, and v is the belt speed

As the belt speed increases, assuming the tensions remain constant, the power transmitted also increases

However, there's a practical limit to this, because at very high speeds, centrifugal force increases and reduces the effective friction and tension difference

But initially, with an increase in speed, the power transmitted increases

frame of the question is not correct.
Most logical answer is friction decreases.
Simply due to the fact that decrease in friction will cause slip of belt ergo reduction in power transmitted.

C is correct, practically speed increases than slip increases and so power decrease.
