    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

    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??
