Hello students, so in another galaxy, the millimillikin oil drop experiment was done and the charge was calculated in the unit of electrinos i .e.
00:22
El.
00:23
So, for 4 drops, it was suppose for a, it was 5 .52 into 10 to the power minus 14.
00:30
For drop b, it was 2 .30 into 10 to the power minus 14.
00:35
And for drop c, it was 5 .98 into 10 to the power minus 14.
00:39
And for drop d, it was 2 .76 into 10 to the power minus 14.
00:43
So, to find the charge of one electron, we have to take the hcf of 5 .52, 2 .30, 5 .98 and 2 .76.
00:56
So firstly, to take the hcf, we will multiply all numbers by 100 to make it a whole number.
01:07
So, the numbers are now 5 .52, 2 .30, 5 .98 and 2 .76.
01:14
So, if we take the lcm, prime factorization, it will come as something like this and 23, 12, 5, 13, 6...
