Question

A particle of mass m = 5 units is moving with uniform speed V = 3 2 units in the X Y plane along the line Y = X + 4 . The magnitude of the angular momentum about origin is, Zero, 60 units, 7 . 5 units, 40 units

MARKS App · Accepted Answer

Angular momentum = momentum × perpendicular distance. L = m v b cos ⁡ θ = 5 × 3 2 × 4 × cos ⁡ 45 o L = 60 kg m 2 s - 1
