Determine the x-intercept and y-intercept of 3x - 6y = 12.(Points : 2) (9, 0) and (0, -3) (4, 0) and (0, -2) (-4, 0) and (0, 4)

physics
Three charged particles are placed at the corners of an equilateral triangle of side d = 1.40 m (Fig. 16-53). The charges are Q1 = +4.0 µC, Q2 = -7.0 µC, and Q3 = -6.0 µC. Calculate the magnitude and direction of the net force on each due to the other two.

You have three identical charged spheres, each with a charge of 2.80 µC. You have arranged them so they are each at the corners of a square that measures 4m on a side. Find the magnitude of the electric field at the "empty" corner. (The corner with no charged s...
