Answer:

The velocity is #8.37xx10^6m/s#

Explanation:

The relation here is

#p = h/(lambda)#

where #lambda# is the wavelength of the electron.

Also, since the classical definition of momentum states that

#p=mv#

We can write

#mv=h/(lambda)

or #v=h/(mlambda)#

Now the numbers

#v= (6.63xx10^(-34))/((9.1 xx10^(-31))(8.7xx10^(-11))##=8.37xx10^6m/s#
