A coaxial cable made up of two conductors. The inner conductor is solid and is of radius R1 and the outer conductor is hollow of inner radius R2 and outer radius R3. The space between the conductors is filled with air. The inner and outer conductors are carrying currents of equal magnitudes and in opposite directions. Then the variation of magnetic field with distance from the axis is best plotted as

Positive point charge q =+8.00μC and q’ = +3.00 μC are moving relative to an observer in Fig. The distance d is 0.120m. When the two charges are at the locations shown in the figure, what are the magnitude and direction of the net magnetic field they produce at point P? (Take v = 4.50× 10^6 m/s and v’ = 9.00 × 10^6 m/s )
