1.6×10⁻¹⁵ J or 10000 ev

Explanation:

E = eV Equation 1

Where E = Energy of the electron, V = Potential difference, e = charge on an electron.

Given: V = 10 kv = 10×100 v = 10000 v,

Substitute into equation 1

E = 10000 ev

If 1 ev = 1.6×10⁻¹⁹ J,

Then, 10000 ev = 1.6×10⁻¹⁹×10000 = 1.6×10⁻¹⁵ J.

Hence the kinetic energy of the electron = 1.6×10⁻¹⁵ J or 10000 ev
