Concept:According to classical electrodynamics, a static charge produces only an electrostatic field, and a charge moving at constant velocity produces steady electric and magnetic fields. An accelerated or oscillating charge radiates electromagnetic waves.
Formula / Reaction:$$P_{\text{rad}} = \frac{q^2 a^2}{6\pi \varepsilon_0 c^3} \quad \text{(Larmor Formula)}$$
Solution:- An accelerating charge creates time-varying electric fields, which induce time-varying magnetic fields.
- This continuous regeneration produces self-propagating electromagnetic waves traveling outward at speed \(c\).
Why other options are incorrect:- Opt_A: Stationary charges produce only static electric fields.
- Opt_B: Charges with uniform velocity produce steady magnetic fields without radiation.
- Opt_D: Unaccelerated motion does not radiate electromagnetic energy.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
