In this problem, we have been given that there is an electron which is moving in the region of uniform electric field and the magnitude of the electric field that is given as 315 newton's per column.
00:15
And we are required to get the acceleration of this electron as it moves in the region of the electric field.
00:23
So here we see that the electron is a negatively charged particle and it will experience force in the position.
00:30
The direction of the electric field.
00:32
So here it will be retarded and the acceleration will be negative.
00:37
And we can see that the force that's acting on the electron is electric field times the charge carried by an electron and that provides the net force on the electron.
00:47
So logically here, e times q is equal to m into a.
00:52
So let's put the values here and we get e as e times q, that's 315 into the charge carried by an electron, which is minus 1 .6 into 10 to minus 19 divided by the mass of the electron.
01:09
That's 9 .1 into 10 raised to minus 31 kg.
01:13
And when we solve this, we're going to get the acceleration coming out to be 5 .54 into 10 raised to 13, and this will be negative value...
