pls help me solve this problem..
charges of +2.0, 3.0 and 8.0µC are placed at the vertices of an equilateral triangle of a side 10 cm. Calculate the magnitude of the force acting on the 8µC charge due to the other two charges.

Add the vector sum of
k*2*8*10^12/0.1^2 and
k*3*8*10^12/0.1^2,
applied 60 degrees apart.
k is the Coulomb constant,
8.99*10^9 N/m^2*C^2
There will be an attraction force in a direction between the two other points of the triangle. It will not bisect the angle, because the forces are unequal.
