Ответ:
Work done to bring three electrons from a great distance apart to 3.0×10−10 m from one another (at the corners of an equilateral triangle) is![2.301*10^{-18} Joules](/tpl/images/0479/8534/0f1db.png)
Explanation:
The potential energy is given by:
U=Q*V
where:
Q is the charge
V is the potential difference
Potential Difference=V=![\frac{kq}{r}](/tpl/images/0479/8534/53143.png)
So,
Where:
k is Coulomb Constant=![8.99*10^9 Nm^2/C^2](/tpl/images/0479/8534/9c9cb.png)
q is the charge on electron=![-1.6*10^-19 C](/tpl/images/0479/8534/895fb.png)
r is the distance=![3.0*10^{-10}m](/tpl/images/0479/8534/88400.png)
For 3 Electrons Potential Energy or work Done is:
Work done to bring three electrons from a great distance apart to 3.0×10−10 m from one another (at the corners of an equilateral triangle) is![2.301*10^{-18} Joules](/tpl/images/0479/8534/0f1db.png)
