Hello students, we are given the following assembly of charges.
00:06
From here we can see that this is 90 degrees.
00:10
Thus, the distance between q1 and q2 will be d square plus h square under root.
00:20
Similarly, the distance between q1 and q3 will also be d square plus h square under root, which is equal to 8 square plus 6 square under root centimeters, which is equal to under root 100 centimeters, which is equal to 0 .1 meters.
00:46
We need to find out what will be the work done to assemble all three charges.
00:53
Now the work then in assembling the charges will be equal to the net potential energy of the system.
01:21
Now the potential energy between two charges is given as k, q1, q2 by r.
01:30
Let's say this is equation 1...
