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 of 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 = 2.10 pC, B = 7.50 pC, and C = -4.10 pC. Given these charges, what would the magnitude and direction of the electric field be at cell A? (1 pC = 1 x 10-12 c.) magnitude What is the equation for the electric field of a point charge? How do you calculate the net electric field at a certain location? What are the components of the fields due to B and C at A's location? N/C direction What are the components of the net electric field? Can you then use these to find the 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 Does the electric field at cell A include the electric field generated by cell A?The field would be unchanged. O The magnitude of the field would be quadrupled. O The magnitude of the field would be halved. O The magnitude of the field would be doubled.

I need help with the first two parts of the question.  Thanks!

Consider the following. 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 of 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 = 2.10 pC, B = 7.50 pC, and C = -4.10 pc. Given these charges, what would the magnitude and direction of the electric field be at cell A? (1 pC = 1 x 10-12 c.) What is the equation for the electric field of a point charge?
