A 0.66 ~kg ball is moving with a speed of 100 ~m / s . The associated wavelength will be (h .=6.6 10⁻³⁴ Js )

Options

  1. A6.6 10⁻³² ~m
  2. B6.6 10⁻³⁴ ~m
  3. C1.0 10⁻³⁵ ~m
  4. D1.0 10⁻³² ~m

Correct answer

C. 1.0 10⁻³⁵ ~m

Step-by-step solution

From de-Broglie equation, = h mv = 6.6 10⁻³⁴ 0.66 100 =10⁻³⁵ ~m
