*72. GO Three point charges have equal magnitudes, two being positive and one negative. These charges are fixed to the corners of an equilateral triangle, as the drawing shows. The magnitude of each of the charges is 5.0 μC, and the lengths of the sides of the triangle are 3.0 cm. Calculate the magnitude of the net force that each charge experiences.

Could I get help seeing how to solve this problem?

three-point charges have equal magnitudes, two being positive and one negative. these charges are fixed to the corners of an equilateral triangle as the drawing shows. the magnitude of each of the charges is 5.5 Uc and the length of the sides of the triangles are 2.5 cm. calculate the magnitude of the net force that each charge experiences. for this question you should have three answers in other words. What is FA, Fb, Fc? 

Three point charges are located on the corners of a right triangle as shown in the Figure, given: 91 (μC) 126 92 (μC) -76.6 93 (μC) 51.2 a (m) 3.00 b (m) 4.00 What is the y-component (unit in N) of the electric force of q₁ onto 93? a 92 O + 91 b y 93 x

Let's say two unknown charges are given to you. You do not know their individual charges, but you know that their total charge is  8.00µC.    You made a test in the laboratory and found that these two charges push each other away with a force of 0.150 N when separated by 0.500 m. What is the charge of the "higher charge" in units of  µC ?

Three point charges have equal magnitudes, two being positive and one negative. These charges are fixed to the corners of an equilateral triangle, as the drawing shows.

34. Go The drawing shows two situations in which charges are placed on the x and y axes. They are all located at the same distance of 6.1 cm from the origin O. For each of the situations in the drawing, determine the magnitude of the net electric field at the origin. -5.0 μC +1.0 µC +2.0 µC -3.0 μC +4.0 μ -1.0 μC +6.0 μC (b) (a)

Four point charges are held fixed in space on the corners of a rectangle with a length of 20 [cm] (in the horizontal direction) and a width of 10 [cm] (in the vertical direction). Starting with the top left corner and going clockwise, the charges are q1=+10 [nC] , q2=−10[nC] , q3=−5[nC] , and q4=+8[nC] .a) Find the magnitude and direction of the electric force on charge q4b) Find the magnitude and direction of the electric field at the midpoint between q3and q4c) Find the magnitude and direction of the electric field at the center of the rectangle.

Consider the following. B 0.500 mm 60.0° (a) Red blood cells often become charged and can be treated as point charges. Healthy red blood cells are negatively charged, but unhealthy cells (due to the presence a bacteria, for example) can become positively charged. In the figure, three red blood cells are oriented such that they are located on the corners of an equilateral triangle. The red blood cell charges are A = 1.80 pC, B = 6.60 pC, and C = -4.40 pC. Given these charges, what would the magnitude and direction of the electric field be at cell A? magnitude N/C direction ° counterclockwise from the +x axis (b) If the charge of cell A were doubled, how would the electric field at cell A change? O The magnitude of the field would be doubled. O The field would be unchanged. O The magnitude of the field would be halved. O The magnitude of the field would be quadrupled.
