Out of the following options which one can be used to produce a propagating electromagnetic wave?

1. A stationary charge               

2. A chargeless particle

3. An accelerating charge         

4. A charge moving at constant velocity

Statement I: A changing electric field produces a magnetic field.

Statement II: A changing magnetic field produces an electric field.

(1) If both statement-I and Statement-II are true, and Statement-II is the correct explanation of Statement-I.

(2) If both Statement-I and Statement-II are true but Statement-II is not the correct explanation of Statement-I.

(3) If Statement-I is true but Statement-II is false.

(4) If Statement-I is false but Statement-II is true.

The relation between electric field E and magnetic field intensity H in an electromagnetic wave is:

(1) E = H

(2) $E=\frac{{\mu }_0}{{\epsilon }_0}H$

(3) $E=\sqrt{\frac{{\epsilon }_0}{{\mu }_0}}H$

(4) $E=\sqrt{\frac{{\mu }_0}{{\epsilon }_0}}H$

Source of an electromagnetic wave is

(1) A charge moving with constant velocity

(2) A charge at rest

(3) A charge moving in a circular orbit

(4) Charges cannot produce an EM wave

An accelerated charge :

(1) emits an electromagnetic wave

(2) does not emit electromagnetic wave

(3) produces a gravitational field

(4) None of these
