Find the magnitude and direction of the force on the upper right charge due to this charge. Force between unlike charges is attractive so direction is down. The x component is obviously zero, the y component is -90 N since its down. N Sketch the net force on the figure above. Find angle by using inverse tangent.
Direction is below the x axis as shown in the figure.
Three charges are arranged around the sides of a right triangle as shown. We wish to find the force on Q 2 . Sketch the force vector for F 2,3 . Predict the direction of the net force on Q 2 and sketch this vector. Angle made by the force from the x- axis is the same as the angle made by the triangle which the three charges form.
