QUESTION 2 [2+2+1=5 MARKS]
An electric charge Q=+6µc is moving with velocity of v=(3.2×10$^6$m/s) î + (1.8×10$^6$m/s) ?. At a moment, this
charge passes the origin of a coordinate.
a) Find the B vector at points M=(-0.3m, +0.4m, 0.0m) and N=(+0.2m, +0.1m, -0.5m). Use unit vectors to
express magnetic field vector.
b) Determine if at any point(s) P= (+0.6m, +0.3m, 0.0m) and S= (+0.2m, +0.0m, -0.5m) is the magnetic field
zero.
c) Determine the angle that B vector makes with the Z-axis at point N, in part (a).
