Wonderful teaching ❤ The final recap was awesome 👍 It makes me revise one more time 😊 Thank you so much mam. Tomorrow is my "Electromagnetic fields and waveguides" subject semester examination ... Thanks a lot ❤.
I usually watch TH-cam videos on 2x speed but this video i have watched with normal speed because it was very interesting because it feels like you know me very well. My every doubt you knew it was like that. Again thank you mam, i do not have now nothing to give you😔.
Let take two identical positive charges q1 and q2. There are four points (a), (b), (c), (d) . q1 was initially located at point (a), and q2 was at point (d). Distance between (a) to (d) is taken 1 lightsecond. Distance between (b) and (c) is also about 1 lightsecond ( a little less) (a)...(b)................(c)...(d) q1.................................q2 q1is moved from (a) to (b) toward q2, and in a similar way, q2 is moved from (d) to (c) toward q1. Let say they both were pushed for half a second. (For Energy given) Force on q1=Kq1q2/r^2 (For energy output) Force on q2 =Kq1q2/r'^2 When we think about r, we found that it would be somewhere between distance of (a) - (d) and (b) - (d), as the electric field of q2 will be the same there for 1 second. But for r′, it is between (a)-(d) and (b) - (c), so r>r′. Therefore, the force on q2 is greater. Assume that you are q1 and are pushed for 1/2 second over a very short distance. You will find that field of q2 were the same there for that time period as a result of the velocity of the electric field. So, the q2 for q1 was at (d) during push. Thus, q1's average distance from q2 was somewhere between (a) - (d) and (b) - (d). However, for r′ taken for force on q2 for receiving signal was different from r. Here, I am q2 and was moved at the same time, but when your changed electric field reached me after 1 second, I was also moved closer. So, for me, you moved closer, and I also moved a little closer to you, which makes my average distance from q1 less than r. Seems like output energy(signal) was more than input given on q1. Tell me how the velocity still not violating the law of conservation of energy
Mam i have one doubt the formula for h vector dow h /dow t =1/2 dow h^2/ dow t or t ^2. we should t or t^2 in the formula please reply mam i have exam tomorrow
Madam while you told about the identities you have written in 2nd identity as( H.dh/dt=1/2.dH^2/dt^2) But in the explanation you have written d(H^2)/dt only madam is it correct or wrong madam?
Mam ap ko phir jo identity hy waha sy t sy square hatana chahiye because ap ny to just dt k respect mai differentiate kia na k dt square k respect mai?

Let take two identical positive charges q1 and q2. There are four points (a), (b), (c), (d) . q1 was initially located at point (a), and q2 was at point (d). Distance between (a) to (d) is taken 1 lightsecond. Distance between (b) and (c) is also about 1 lightsecond ( a little less)
(a)...(b)................(c)...(d)
q1.................................q2
q1is moved from (a) to (b) toward q2, and in a similar way, q2 is moved from (d) to (c) toward q1. Let say they both were pushed for half a second.
(For Energy given) Force on q1=Kq1q2/r^2
(For energy output) Force on q2 =Kq1q2/r'^2
When we think about r, we found that it would be somewhere between distance of (a) - (d) and (b) - (d), as the electric field of q2 will be the same there for 1 second. But for r′, it is between (a)-(d) and (b) - (c), so r>r′. Therefore, the force on q2 is greater.
Assume that you are q1 and are pushed for 1/2 second over a very short distance.

Madam while you told about the identities you have written in 2nd identity as( H.dh/dt=1/2.dH^2/dt^2)
But in the explanation you have written d(H^2)/dt only madam is it correct or wrong madam?
At 2:16 sec, i have explained it. It is correct only
