Answer:
Electric field, E = 936.19 N/C
Explanation:
It is given that,
Charge 1,
Charge 2,
Distance between them, d = 3 mm = 0.003 m
Torque,
Angle between electric field and line connecting the charge,
We need to find the torque exerted on the dipole. The torque experienced by the dipole in the electric field is given by :
p is the dipole moment,
E = 936.19 N/C
So, the magnitude of electric field on the dipole is 936.19 N/C. Hence, this is the required solution.
Explanation:
Let us assume that Z is the energy transported across an area of per hour by an electromagnetic wave with an r.m.s speed of 21.5 V/m.
Therefore, first we will calculate the current as follows.
I =
=
= 0.441 J
Therefore, we can conclude that 0.441 J energy is transported across a given EM wave.
