A particle is represented by the following wave function:

ψ(x) =0      x<−1/2
ψ(x) =C(2x + 1)      −1/2 < x < 0
ψ(x) =C(−2x + 1)      0 < x < +1/2
ψ(x) =0      x > +1/2

(a) Use the normalization condition to find C ?

(b) Evaluate the probability to find the particle in an interval of width 0.01 at x = 0.1 (that is, between x = 0.095 and x = 0.105.)(No integral is necessary for this calculation.)

(c)Evaluate the probability to find the particle between x=0.19 and x=0.35.

(d) Find the average values of x and x2, and the uncertainty of x: Δx=√(x2)av-(xav)2

3. (a) Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight. Assuming equal point charges (only an approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a9.00 mg piece of tape held 1.10 cm above another. (The magnitude of this charge is consistent with what is typical of static electricity.)
