Rotational motion, relative angular momentum
p = -1/4 and n = 1/3.
But when we take angular momentum of A w.r.t. B, why don't we also take relative velocity (v of a w.r.t b)? We take relative position clearly, but not relative velocity?...
Ray optics, silvering of lens sign convention
I've attached the solution's sign convention method attached. But why is this the case?
Ray optics, lens maker's formula with different medium on either side
What do we take as relative refractive index? Why is the solution taking it as air for all 3 lenses?
Polarisation
why is b incorrect at 90deg second polariser will be horizontal and first one is vertical so it will cancel all light and I = 0
Maximum Height of a Ballistic Pendulum
Consider the given ballistic pendulum. For the given setup, no torque is present on the sphere w.r.t the center of the sphere, so shouldn't the rotational component of K.E. be zero?
why this?
why does the third has the answer as br on 1st carbon shouldnt it be 2nd cuz of markonikov rule?
