Hello everyone, so alpha particle is there and it is moving in a circular path.
00:06
So the radius of that circular path is in 7 .5 cm and magnetic field v is 1 .5 tressin and chance q is equal to plus 2.
00:16
Now we have to find the four parts of this portion.
00:19
So first part is here to that a speed of alpha particle.
00:24
So v is here.
00:27
Rqb over f.
00:29
So we'll put the value z.
00:31
R 0 .075 multiplied by charge fuel, 2 multiplied by 1 .6 multiplied by 10x4 minus 9.
00:41
Magnetic field, this is 1 .5 tesla over mass and.
00:47
So here, mass am, is 6 .64 multiplied by 10x4 minus 20 .7.
00:55
So, we are getting the velocity.
00:58
So this is equal to 5 .4 multiplicity 10 -inch to power 6 meta -person...
