Properties of Eigen wave function

• Single valued

• Finite

• Continuous

• Infinite

The basic principle behind quantum mechanics is

(a)  

The probability density is the

• Square root of wave function

• Absolute value of wave function

• Inverse of wave function

• Absolute square of wave function

  A man of mass 50 kg jumps to a height of 1 m. His potential energy at the highest point is (g = 10 m/s2)

• 50J
• 500J
• 12J
• 30J

According to the law of moments, if a number of coplaner forces acting on a particle are in equilibrium, then

• the algebraic sum of their moments about any point in their plane is zero
• the algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point.
• their lines of action are at equal distances
• their algebraic sum is zero

The Branchistochrone problem is to find

• shape of a curve
• blength of a curve c.
• elasticity of a curve electrons
• width

Probability of finding the particle in a given space is given by

• Wave function

• Probability amplitude

• Probability density

The minimum energy required for photoelectron to escape from metal plate in a photocell is called 

•       Work function

    

• Threshold frequency

      

• Stopping voltage

• Plancks constant

The square of the magnitude of the wave function is called_________

• Current density

• Probability density

• Zero density

• Volume density

The frequency of Harmonic oscillator is given by

• [1/2p(k/m)5/2]
• [1/2p(k/m)3/2]
