Already with Lagrangians you overcomplicate complicated task, but Lagrangiam mechanics can not explain Solar system rotation because Poincare perturbation of three body problem is unsolvable.
1:45 is wrong. Minus Gradient dot E would be correct and would lead to a scalar expression like what you have; if the subject of the expression were not representing force. Minus Gradient E would lead to a vector. So the expression is wrong. The correct resultant value for force would be a vector.
It can be clearly seen that there is no dot between del operator and the function. Meaning, it denotes the gradient of a scalar field and thus produces a vector. The later expression lacks the respective unit vectors.
@@laxminarayanbhandari855 Nice... looks like they fixed the leftmost piece of the expression in the time between 4 weeks ago and now. The expression on the far right is still wrong.
