Q. Two coils $P$ and $Q$ are placed co-axially and carry current $I$ and I’ respectively
A) If $I^{'} = 0$ and $P$ moves towards $Q$, a current in the same direction as I is induced in $Q$
B) If $I = 0$ and $Q$ moves towards $P$, a current opposite in direction to that of I’ is induced in $P$
C) When $I \neq 0$ and $I' \neq 0$ are in the same direction, then two coil tend to move apart
D) None of the above
