The path of a charged particle in a plane perpendicular to a uniform magnetic field is:
Explanation
When a charged particle moves perpendicular to a uniform magnetic field the magnetic force is always perpendicular to the velocity and provides a centripetal force. That constant perpendicular force makes the particle move in a circle at constant speed, so the path is circular.
Magnetic force acting on a charge at rest is:
Explanation
Magnetic force on a charge is F = q(v × B), so if the charge is at rest (v = 0) the cross product is zero and no magnetic force acts. Therefore the magnetic force on a stationary charge is zero.
If mass of a charged particle is doubled, cyclotron frequency becomes:
Explanation
Cyclotron frequency is ω = qB/m (or f = qB/2πm), so frequency is inversely proportional to mass. Doubling the particle's mass halves the cyclotron frequency.
Electric field intensity of infinite charge sheet:
Explanation
An infinite charged plane produces a constant electric field on each side with magnitude E = σ/(2ε0), independent of distance, because Gauss's law gives equal flux through two faces of a Gaussian pillbox. Thus the correct expression is σ/(2ε0).
Stability of radioactivity element is determined by:
Explanation
The decay constant (λ) quantifies how quickly nuclei decay: a larger λ means faster decay and less stability, while a small λ indicates greater stability. Therefore the stability of a radioactive element is characterized by its decay constant.
1 kWh is equal to:
Explanation
1 kilowatt-hour is 1 kW × 3600 s = 1000 J/s × 3600 s = 3.6×10^6 J, which is 3.6 MJ. So 1 kWh equals 3.6 megajoules.
