Question

A point object of mass m is moving with a constant velocity
v0 iˆ . When it is at a location (a,b)where a > 0 and b > 0 , its angular momentum about origin
(a) is equal to mv0b (b) is directed in the −Z axis always
(c) stays unchanged (d) all the above

Angular moment of particle w.r.t origin = linear momentum x perpendicular distance on line of action of linear momentum from origin. = mv × a = mva = constant . 

Answer 2

Answer:

(c) stays unchanged

Explanation:

A point object of mass m is moving with a constant velocity

v0 iˆ . When it is at a location (a,b)where a > 0 and b > 0 , its angular momentum about origin

(a) is equal to mv0b (b) is directed in the −Z axis always

(c) stays unchanged (d) all the above
