P.072. My Notes Ask Your Teacher Three particles with charges of 1.0 HC 1.0 HC, and 0.50 HC are placed at the corners A, B, and Cof an equilateral triangle with side length s 0.54 m as shown in the figure below. Find the net force on the charge at point C. Express your answer in vector form. Assume the tx direction is to the right and the +y direction is upward 1.0 0.50 Need Help?

Explanation / Answer

Force due to top charge = kq1q2/r^2 = 9e9*1e-6*0.5e-6/0.54^2

= 0.015432 N

Now the force due to left charge will also be of same magnitude. There is an angle of 120 degree between these two forces.

So the resultant will be 0.015432 N at 60 degree with -x axis.

F = - 0.015432*cos 60 degree i -  0.015432*sin 60 degree j

= -0.007716 i - 0.01336 j N
