Aisha sets this apparatus and notes the deflection of the rod using two horse shoe magnets differently. Then brings the magnets together and notes down her observations. The rod happens to move faster in the second case.
1. What will Aisha observe in the deflection of rod?
a. There is no deflection in rod seen.
b. The conductor moves slower than when single horse shoe magnet is used
c. The conductor moves faster than when single horse shoe magnet is used
d. The conductor moves very slightly then stops
2. If the conductor is accelerated more, what will be the force required to move it?
a. No force is required
b. Same force is required
c. Less force is required
d. More force is required
3. What will happen if the magnetic field is increased in the apparatus?
a. The rod will move with less force and more acceleration
b. The rod will move with more force and more acceleration
c. The rod will move with more force and less acceleration
d. The rod will move with less force and less acceleration
4. What will happen to the speed of the rod on increasing the magnetic field?
a. It increases
b. It decreases
c. It has no change
d. None of the above
5. The force acting on a current carrying conductor placed in a magnetic field increases with increase in Weld strength. True or false?
a. TRUE
b. FALSE
