Calculate the wavelength of an electron whose kinetic energy is 3(10*2...
Because in case of (b) velocity is depend on other two quantities. So sets (b) cannot enter into the list of fundamental quantities in any system of units.The wavelength will be calculated from the De Broglie's relation which is λ = h/ (mxv)where λ is the wavelength, h is the planck's constant, m is the mass of the electron and v is its velocity. For calculating the velocity, we will use the expression E = 1/2 mv^2We are given that E = 3 x 10^-25J. Therefore we get v^2 = 2 x E /mOn substituting the values, we get v = 8.12 x 10^2Hence λ = h/ (mxv) = 6.63 x 10^-34/(9.1 x 10^-31 x8.12 x 10^2) = 8.972 x 10^-7mHence the wavelength of the electron will be 8.972 x 10^-7m

Wavelength = 8.99 × 10^-7m1stlyfrom the rel, KE=1/2mv^2find value of vthat comes out to be 8.1×10^2 ms^-1then by using relλ=h/mvλ= 8.99 × 10^-7m....(^_^)?
