Three charges of +0.1 C each are placed at the vertices of an equilateral triangle of each side 1m. If the energy is supplied at the rate of 1.0 kw, how many hours would be required to move one of the charges on to the mid point of the line joining the other two?
Given `=1/(4piepsilon_0) = 9xx 10^9 N ^2C^-2`
