According to de Broglie equation
Wave length = h/mv = 6.255 x 10 power -34 /(0.1x10) = 6.824 x 10 power -34 m. Answer...................

We know that,
λ = h / mv
h ---> Planck's constant
m ---> Mass of ball
v ---> Velocity of ball
h = 6.626 × 10^-34
m = 0.1 kg
v = 10 m/s
Substituting these values in the equation.
.: λ =
(6.626 × 10^-34) ÷ ( 0.1 ×10 )
= 6.626 × 10^-34 m //
