  • momentum is given by p=h/lambda
    As h is constant so p is inversely proportional to lambda. The value of lambda is 0.01 angstrom I.e, 1×102 Angstrom. and angstrom is equals to 10 raised to the power 10. so the equation becomes p=1/1×102×1010. p=1/1×1012
    p=10 raised to the power -12. So the answer is ×10-12.
