Before Clicking on Any Links Check this ! #shorts

One end of the pile of chain falls vertically through a hole in its support and pull the remaining links steadily. The links which are at rest acquire the velocity of the hanging position suddenly and without loving interaction with the remaining stationery links and with the support. If the acceleration a of the falling chain is g//k . Find k . Ignore any friction.

The magnetic induction at any point due to a short magnetic dipole is

Solve the following questions. (Any two ) (i) Check if the points (3,9) , (0,6) and (-4,2) are collinear or not .

The direction of resultant magnetic induction at any point due to a short magnetic dipole is inclined to the axis dipole at an angle

The Sun is seen little before it rises and for a short while after it sets. This is because of

The magnetic potential at any point due to short magnetic dipole is

A boy rolls a rubber ball on a wooden surface. The ball travels a short distance before coming to rest. To make the same ball travel longer distance before coming to rest, he may

A constant current exists in an inductor coil connected to a battery. The coil is short circuited and the battery is removed. Show that the charge flown through the coil aftter the short circuiting is the same as that which flows in one time constant before the short circuiting.

The ratio of magnitude of magnetic induction (B)at any point due to short magnetic dipole and the magnetic potential (V) at that point is given by
