Type: MCQ-numerical-Medium
An automobile engine develops 100 kW power when rotating at a speed of 1800 rpm. The torque delivered by the engine is
A
10²/6π Nm
B
10⁵/6π Nm
C
10⁶/6π Nm
D
10⁸/6π Nm
Correct Answer
Option B
Detailed Explanation
The power P is 10⁵ W and the angular speed ω is 60π rad s⁻¹. Torque τ is given by τ = P/ω = 10⁵/60π = 10⁵/6π Nm.
