Lenz Law: Practice Problem & Solution

As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. Due to this induced electromotive force, induced current and induced charge in the coil is E, I and Q respectively. If the speed of the magnet is doubled, the incorrect statement is Lenz Law diagram: As shown in the figure, a magnet is
E increases
Q remains same
I increases
Q increases

1. Assertion (A): If a magnet is allowed to fall co-axially through a long copper tube, its acceleration decreases with time. Reason (R): The direction of force on magnet doesn't change when it pass through a tube.  
2. A conducting wire frame is placed in a magnetic field which is directed into the paper. The magnetic field is increasing at a constant rate. The directions of induced current in wires AB and CD are :
3. Two coils carrying current in opposite direction placed co-axially as shown in figure. Now that brought closer to each other, than :
4. Assertion (A): If a bar magnet is moved towards a conducting coil in a direction perpendicular to the plane of coil, the work done in moving the magnet will be more if it is moved faster rather than slower. Reason (R): If the magnet is moved at a faster rate towards the circular coil, then the induced current in the circular coil is more.  
5. Assertion (A): It is more difficult to push a magnet into a coil with more loops. Reason (R): This is because emf induced in each current loop resists the motion of the magnet.
