Question 1 A 5.30 nC charge is located at the origin. What is the electric field at (x, )) = (1.80 cm, 5.10 cm)? O (1.63x10* N/C) i O (5.42x103 N/C) i + (1.54x104 N/C) j O (1.59x1012 N/C) i + (4.49x1012 N/C) j O (1.71x105 N/C) i + (7.54x103 N/C) j Question 2 + d d d The charges in the figure above both have a magnitude of 6.40 nC, and the distance dis 5.70 cm. What is the magnitude of the electric field at the dot? 3.546+04 N/C 1.25E+04 N/C O 2.50E+04 N/C O 1.77E+04 N/CQuestion 3 A S S B C In the figure above, charge A is -4.25 nC, charge B is 17.0 nC, and charge C is-4.25 nC. If s= 3.70 cm, what is the electric field at the dot? O 9.53x104 N/C, 50.80 counter-clockwise from the positive x-axis O 1.63x104 N/C, 45.00 counter-clockwise from the positive x-axis O 9.53x104 N/C, 45.00 clockwise from the negative xaxis O 1.63x104 N/C, 50.80 clockwise from the positive x-axis
