Jatin sir, your daliy news analysis is awesome. I could see the videos interestingly. Actually I will attempt the exam in English but always have a difficulty in English. I lose my interest, when I see English videos. Please make English videos also interesting with simple language.
sir at 6:28, Vslide should be V2sin(beta) + V1sin(alpha). why negative sign is taken?
Sir, why relative velocity is perpendicular to line of action....
sir, why rolling takes place at pitch point only....
