Question

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

MARKS App · Accepted Answer

Angular momentum about the origin L = | r × m v | = ( 4 cos ⁡ 45 ° ) × ( 5 ) × 3 2 = 4 2 × 5 × 3 2 L = 60 units
