Assertion (A): | A charge moving in a circular orbit can produce electromagnetic wave. |
Reason (R): | The source of electromagnetic wave should be in accelerated motion. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
(A) | a varying sinusoidal current flowing through a capacitor |
(B) | an electric dipole, whose size (and magnitude) is oscillating with time |
(C) | a steady current flowing through a toroid |
1. | only (A) | 2. | only (B) |
3. | only (A) & (B) | 4. | (A), (B), (C) |
Statement I: | Electromagnetic waves are radiated when a charged particle undergoes SHM. |
Statement II: | Electromagnetic waves propagate energy in the direction of the electric field of the wave. |
1. | Statement I is incorrect and Statement II is correct. |
2. | Both Statement I and Statement II are correct. |
3. | Both Statement I and Statement II are incorrect. |
4. | Statement I is correct and Statement II is incorrect. |
Statement I: | Charged particles which undergo acceleration or deceleration radiate their energy away. |
Statement II: | Therefore, charged particles moving in circular paths in a uniform magnetic field should also radiate their energy. |
1. | Statement I is true, Statement II is true and Statement I implies Statement II. |
2. | Statement I is true, Statement II is true and Statement I does not imply Statement II. |
3. | Statement I is true, Statement II is false. |
4. | Statement I is false, Statement II is true. |
