Hello everyone, so today i will be solving this question for you.
00:04
Let me write the solution over here.
00:06
So basically in this question we have to calculate the drift velocity.
00:11
Okay, let's say it is represented by vd.
00:14
Okay, now we know that 6 .023 into 10 to the power 23 atoms have mass equal to 63 into 10 to the power minus 3 kg.
00:30
Okay, now number of atoms.
00:36
Per meter cube will be equal to the mass, okay, the number of atoms upon the mass, all right, and into the given, the density given.
00:58
And we will find n equal to 8 .5 into 10 to the power 28.
01:03
These are the number of atoms present per meter cube...
