    56:38 this can also be solved using vectors....
    Magnetic field is going into the plane of the field.
    Therefore, B vector = -Bḱ
    v vector can be resolved as
    v.cos(37°)î + v.sin(37°)j
    Or 4î/5 + 3j/5
    Length vector can be taken
    +lî or -lî as you choose.
    Now solving (v×B).l gives 3/5vBl

    You made this easy to understand. A teacher’s main goal is to teach. If they simplified something that used to be difficult for your kid to understand, let them know they’re good at their job. Better yet, have your kid tell them directly! Hearing the newly discovered confidence in your child’s voice will make the teacher so proud..... So alakh sir is god person for us..... 🎊🎊🥰
    Love u so much... 🥰

    Sir in 55:03, the 2nd question where V is with angle of 37 degree with L vector, we can also solve by resolving the velocity into two components i.e. Vsin37 and Vcos37. Vcos37 is parallel to l vector so e=0. Therefore e will only be due to Vsin37 component i.e. e=BlVsin37=(3BVl)/5. This way is also correct right sir??
