Here, the answer is C. Displacement is the shortest distance covered by a body. In a circular path, the distance between the initial point (Here=P) and the final point (Here=Q) will give you the displacement. Here, Shortest distance between P and Q is PO + OQ = a + a = 2a Hence, the displacement of the cyclist would be 2a.

Here, the answer is B. Since in a magnetic needle the arrow head is the North Pole, it will point towards the South Pole of the left hand side magnet and the other end of the magnetic needle (i.e; South Pole) will point towards the North Pole of the right hand side magnet.This is because like poles repel and unlike poles attract each other. Hence,the polarity of the end P of the right hand side magnet is North.
