Question

A particle of mass 5 g is moving with a speed of 3 2 c m s - 1 in X-Y plane along the line y = x + 4 . The magnitude of its angular momentum about the origin in g c m 2 s - 1 is, Zero, 60, 30, 30 2

MARKS App · Accepted Answer

Given y = x + 4 When x = 0 , y = 4 c m And y = 0 , x = - 4 c m Perpendicular distance O C = O A sin ⁡ 45 o = 4 × 1 2 = 2 2 c m Angular momentum = m v O C = 5 3 2 2 2 = 60 g m c m 2 s - 1
