In this question we talk about physicist.
00:03
So here we talk about physicist that is designate the cyclotron.
00:09
Physicist that designate the cyclotron and to accelerate the proton.
00:14
To accelerate protons and 1 ten of the speed.
00:19
Speed here which is 1 ten of the speed of light.
00:26
Now or we can say c divided by 10.
00:29
Now the magnetic field has a strength.
00:32
So magnetic field b which is equal to 2 .3 tesla.
00:36
In the first part of this question our target is to find determine the rotational period.
00:42
So we want to find rotational period.
00:45
So tr that we want to find is in the second of the circulating protons.
00:55
So let's find out rotational period.
00:58
So here we can write.
01:00
Talk about charged particle moving in the magnetic field.
01:03
So we can write force here is qvb which is equal to we can write mv square divided by r.
01:08
Now we simplify this and we can write the b multiplied by q which is equal to we can write m multiplied by omega.
01:14
Now again we simplify this and we can write omega which is equal to here b multiplied by q divided by m.
01:24
That substitute value into this formula.
01:25
So here you can write 2 .3 multiplied by charge value which is 1 .6 multiplied by 10 raised to minus 19...
