Question

Part A -

Calculate the magnitude of the electric field at the center of a square 42.5 cm on a side if one corner is occupied by a −38.3 μC charge and the other three are occupied by −27.1μC charges.

Express your answer to three significant figures and include the appropriate units.

Part B-

Choose the correct direction of the electric field at the center of the square.

a. perpendicular to the diagonal passing through −38.3 μC charge

b. toward to −38.3 μC charge

c. outward of −38.3 μC charge
