So, in this question we have the given data that is energy.
00:05
So, energy is equal to 0 .5 kev.
00:09
So, we'll convert it into, so this will be 8 .01 into 10 to the power minus 17 i.
00:16
So, we know that that e is equal to, energy is equal to half of mv square by the formula.
00:25
So, from this of mv square.
00:29
So, from this v will be equal to root over 2e by m.
00:36
Now, i'll put the value here.
00:37
So, this will be root over 2e value is 8 .01 into 10 to the power minus 17 divided by m value is given that is 1 .67 into 10 to the power minus 27...
