The correct statement.

Explanation of Solution
Introduction:
The radioactive particles alpha, beta and gamma rays are formed due to radioactive decay. The alpha particles consists two protons and two neutrons. The beta particle consists one electron. The gamma rays are massless energy.
The nucleus of helium atom consists two proton and two neutrons in the nucleus. The alpha particles also consists two protons and two neutrons, so the alpha particle is same as the helium atom. The alpha particle is the byproduct of radioactive decay. So, Helium atom also. So, the first statement is correct.
Conclusion:
Thus, the first statement is correct.

- You are tasked with designing a parallel-plate capacitor using two square metal plates, eachwith an area of 0.5 m², separated by a 0.1 mm thick layer of air. However, to increase the capacitance,you decide to insert a dielectric material with a dielectric constant κ = 3.0 between the plates. Describewhat happens (and why) to the E field between the plates when the dielectric is added in place of theair.arrow_forwardCalculate the work required to assemble a uniform charge Q on a thin spherical shell of radiusR. Start with no charge and add infinitesimal charges dq until the total charge reaches Q, assuming thecharge is always evenly distributed over the shell’s surface. Show all steps.arrow_forwardRod AB is fixed to a smooth collar D, which slides freely along the vertical guide shown in (Figure 1).

- Consider a uniformly charged ring of radius R with total charge Q, centered at the origin inthe xy-plane. Find the electric field (as a vector) at a point on the z-axis at a distance z above thecenter of the ring. Assume the charge density is constant along the ring.arrow_forward3) If the slider block C is moving at 3m/s, determine the angular velocity of BC and the crank AB at the instant shown.
