Electric Potential and Capacitance · Potential energy

A point charge of 10−810^{-8} C is placed at origin. The work done in moving a point charge 2 μ2\ \muC from point A(4, 4, 2) m to B(2, 2, 1) m is J. (14πϵ0=9×109\dfrac{1}{4\pi\epsilon_0} = 9\times10^{9} in SI units)
  1. (1)45×10−645\times10^{-6}
  2. (2)0
  3. (3)30×10−630\times10^{-6}
  4. (4)15×10−615\times10^{-6}
