Question

the bob of a simple pendulum is charge and displaced slightly from vertical main position and released then it produces (a) an electric field only (b) a magnetic field only (c) both electric and magnetic fields(d) the electric field magnetic field in electromagnetic wave​

Answer 1

Answer:

b. the magnetic field.

Because the Bob moves uniformly about its axis to produce a magnetic field .

It does not produces electric field because there is no change in the matter, if the matter changes then there will be change in atoms present in the matter due to which it their will be a collision of electron in the atoms .As because of this reason electric field will be produced.
