Correct Answer - Option 3 : 8.3 kW

__Concept__:

Power transmitted by a belt is given by:

**P = (T1 – T2) × v**

where P = power transmitted through belt, T_{1} = tension in the tight side, T_{2} = tension in the slack side, v = velocity of belt

__Calculation__:

__Given:__

T1 = 1500 N, T_{2} = 1000 N, v = 1 km/min = 16.68 m/s

Now, from the given formula we have,

P = (1500 - 1000) × 16.68 = 8340 W = 8.3 kW

**P = 8.3 kW**
