The formula for calculating the Broglie wavelength of a particle is:
λ = h/mv
where λ is the wavelength, h is Planck's constant (6.626 x 10^-34 J.s), m is the mass of the particle, and v is the velocity of the particle.
In this case, we are given the velocity of an electron, which has a mass of 9.109 x 10^-31 kg. Plugging in these values, we get:
λ = (6.626 x 10^-34 J.s)/(9.109 x 10^-31 kg x 10^5 m/s)
λ = 7.27 x 10^-11 m
Therefore, the Broglie wavelength of an electron with a velocity of 10^5m/s is approximately 7.27 x 10^-11 m.
