Question

A particle is moving along a straight line with increasing speed its angular momentum

Answer 1

Answer:

Zero

Explanation

The body is in translational motion and there is no rotational motion

Here 'r' the perpendicular distance is 0 therefore angular acceleration = p× r becomes 0

Answer 2

Answer:

A particle is moving along a straight line with increasing speed its angular momentum is?

Explanation:

• When the particle is moving along the straight line with increasing speed its angular momentum goes on increasing and goes on decreasing.
• It may increasing or decreasing it completely depends on the direction of the motion remains zero.
• Angular momentum=
• L= mvr1, were r1 is the perpendicular distance of v from the point.
• So the is on the line itself, therefore r1 is also equal to zero and angular momentum is also zero. That is r1= 0 and L= 0.
• It is, not only about mvr but it is mvr sin theta, where theta is angle between r and v.
• When the particle is moving along the straight line with increasing speed its angular momentum goes on increasing and goes on decreasing. It may increasing or decreasing it completely depends on the direction of the motion remains zero.
