Answer:
Explanation:
The potential energy of a system of two charges is given by the expression
[tex]\frac{K\times Q_1\times Q_2}{R}[/tex]
Q₁ and Q₂ are two charges and R is distance between the charges.
Given Q₁ = Q₂ = 3.7 X 10⁻⁶ , R = .8 and K = 9 x 10⁹
Putting these values in the equation we have,
[tex][tex]\frac{9\times 10^9\times 3.7\times10^{-6} 3.7\times 10^{-6}}{.8}[/tex][/tex]
Potential energy = 154.01 x 10⁻³ J
This energy have been spent to bring these repelling two charges at this close distance . The energy spent have been stored as potential energy here which has been calculated.
