Hey buddy, great video! subscribed. I have a question though... How are you supposed to know whether the question is related to flemings right hand rule or left hand rule since I always have that confusion and I end up getting the question wrong.
if u use Fleming's left hand rule on D: index finger downward (N to S) middle finger into page (current opposite to electron) the thumb will point to the right not to the left. and make sure ur using ur left hand
Thank you mr!

Brother in q 22...Critical angle is 1/sinc where c is the refractive index of the medium...how is c correct the?
this is simple math
u can just reverse the ratio
the original is refr. index is 1/sin c
so sin c = 1/ref index
