Ahertzian dipole antenna in free space has /= 0.02. the following are in far-field: (a) what value of current i is necessary to radiate a total power of 60 mw? (b) what is the ratio of the magnetic field intensity, h, at the polar angles 0 = 10 degrees and 80 degrees (c) what fraction of the total radiated power is contained in the region 0 < 60 degrees (d) what is the radiation resistance, rrad?

c) up is the direction the magnetic force is acting on the charge.

does anyone know or what?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

magnets not strong enough
