1wavelength of the moving ball=h/mv =6.626x10-34/0.1x100
=6.627x10-35m

1The atomic number (Z) of an element whose wavelength is l is 11. The atomic number of an element whose
wavelength is 4 l is equal to
ans; 6
method
(Z -1)2l = cons tan t \(102 )l= 4l(Z -1)2ÞZ = 6 .
hope dis wld help .
1i don kno anythn abt dis,.........
got it frm a source......
