Two short antennas each of length 10cm at the origin carry identical currents of I = 5 Sin (wt). One is in the az direction and the other one is in the ay direction. If the frequency of the antenna is 60 MHz then calculate
(a) Es (the spatial part of E) at a point R (0, 1000, 0)
(b) E at a point R (1000,0,0) at time t= 1.57 seconds
