Correct option is C
The correct answer is: (c) [M L² T⁻¹]
• Angular impulse is defined as: Angular Impulse = Torque × Time
• Torque (τ) = Force × Perpendicular distance
→ [M L T⁻²] × [L] = [M L² T⁻²]
• Angular Impulse = [M L² T⁻²] × [T] = [M L² T⁻¹]
So, the dimensional formula of angular impulse is [M L² T⁻¹].
Information Booster:
• Linear impulse = Force × Time → [M L T⁻¹]
• Torque = [M L² T⁻²]
• Angular momentum = Moment of inertia × Angular velocity → [M L² T⁻¹]
• Angular impulse = Change in angular momentum
• Both angular impulse and angular momentum have same dimensions
