Hi, here in this given problem three charge particles are arranged at the x -axis as given here.
00:11
The first charge particle which is positive that has been kept at the origin.
00:17
This is q1.
00:19
Then a negative charge particle q2 has been kept at a position 12 cm along x axis and the third charge particle which is again positive.
00:32
3, it has been kept at a position 15 cm along the x -axis.
00:41
Values of the charges, q1 that is equal to plus 9 .9 micropoleum.
00:50
Q2, that is minus 5 .1 micropoleum.
00:56
Q3 is plus 4 .4 microtum.
01:00
Now, we have to find net force experienced by the charge q3 and this q3 will be experiencing two forces.
01:13
One, the force of attraction due to q2 and that is f at 3 due to 2 and another will be force of repulsion due to q1.
01:27
F at 3 due to 1.
01:30
So the net force will be given by f3 is equal to f at 3 due to 2 as it will be greater than f3 1...
