Question

The wavelength associated with a golf ball weighing 200 g and moving at a speed of 5 m/h is of the order (a) 10⁻¹⁰ m (b) 10⁻²⁰ m(c) 10⁻³⁰ m (d) 10⁻⁴⁰ m

Answer 1

Wavelength=h/mv,

=6.6*10-34 j-s/ 200*10-3kg*5/3600

=3.3*10-31*36/5

=118.8*10-31/5

=23*10-31

=2.3*10-31 (ans)

=10-30 (ans)
