Answer to Problem 63CP
The energy of the state will be
Explanation of Solution
Write the Schrodinger equation for a simple harmonic oscillator.
Here,
Write the given wave function.
Differentiate the above equation with respect to
Differentiate again the above equation.
Conclusion:
Rewrite the Schrodinger equation by substituting the equations for
Compare the coefficients of
Therefore, the energy of the state will be
(b)
The position at which there is no any possibility to find a particle.
(b)

Answer to Problem 63CP
Particle cannot be found at
Explanation of Solution
The possibility of finding a particle depends on the value of wave function. A particle cannot be found at a position where wave function vanishes. The wave function vanishes at
Therefore, the particle cannot be found at
(c)
The most probable position for finding the particle.
(c)

Answer to Problem 63CP
The maximum probability for particles are at
Explanation of Solution
Point of maximum probability is a point of maxima.
Write the condition to be satisfied at the point of maximum probability of finding the particle.
Conclusion:
Substitute
Rewrite the above relation in terms of
Therefore, the maximum probabilities for particles are at
(d)
The value of

- A block of mass m = 3.00 kg situated on a rough incline at an angle of 0 = 37.0° is connected to a spring of negligible mass having a spring constant of 100 N/m (see the figure below). The pulley is frictionelss. The block is released from rest when the spring is unstretched. The block moves 11.0 cm down the incline before coming to rest. Find the coefficient of kinetic friction between block and incline. k=100 N/m Ө marrow_forward23.

- 9. Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.arrow_forwardIn the movie Fast X, a 10100 kg round bomb is set rolling in Rome. The bomb gets up to 17.6 m/s. To try to stop the bomb, the protagonist Dom swings the counterweight of a crane, which has a mass of 354000 kg into the bomb at 3.61 m/s in the opposite direction. Directly after the collision the crane counterweight continues in the same direction it was going at 2.13 m/s. What is the velocity (magnitude and direction) of the bomb right after the collision?arrow_forwardDon't use aiarrow_forward
