Hey everyone, welcome back.
00:01
In this question we are given with two different objects.
00:04
The first object, or let's say object a, is moving in a circle of radius r with velocity v.
00:10
So let's say this is the object a and this is moving with the velocity v in a circle of radius r.
00:18
Okay, whereas there is another object, object b, which is moving in a circle of half of the radius of the circle of a.
00:29
So, its radius is r by 2 and this one is moving with velocity to v.
00:34
So we have to find out, in the first part we have to find out the ratio of time period of a to ratio of time period of b.
00:41
Okay, now as we know that time period of a will be 2 pi divided by angular velocity of a.
00:47
Similarly, time period of b will be 2 pi divided by time period of angular velocity of b and that is coming out as omega b over omega a...
