What is the probability of finding a particle in a well of width ∝ at a position \( \frac{\alpha }{4} \) from the wall if n = 1, if n = 2, if n = 3. Use the normalized wavefunction ψ(x,t) =\( \left ( \frac{2}{a} \right )^{\frac{1}{2}} \) sin\(\left ( \frac{n\pi x}{a} \right )e^{-\frac{iEt}{h cut}}\).

Two large parallel plates are separated by a distance of 5 cm. The plates have equal but opposite charges that create an electric field in the region between the plate. An α particle ( q = 3.2 × 10^-27 kg) is released from the positively charged plate, and it strikes the negatively charged plate 2 × 10^-6 second later. Assuming that the electric field between the plates is uniform and perpendicular to the plates. what is the strength of the electric field?
