Question 1 Two charged disks that are 25.3 cm apart face each other. The radius of each disk is 12.7 cm, the charge on the left disk is -2.50 nC, and the charge on the right disk is +2.50 nC. What is the magnitude of the electric field at the midpoint between the two disks? O 3.93x103 N/C O 1.64x103 N/C 987 N/C O 410. N/C Question 2 A water molecule has a permanent dipole moment of 6.20x10-30 Cm, and if you put one in an electric field it will feel a torque and try to rotate (this is essentially how a microwave oven works, although that electric field oscillates). What is the torque on the molecule if its dipole moment is oriented at 37.5 with respect to the electric field, which has a strength of 2.90x104 N/C? 1.80x10-25 Nm O 7.99x10-26 Nm 1.09x10-25 Nm 3.56x10-26 Nm Question 3 A parallel-plate capacitor is formed of of two 7.00 cm x 7.00 cm plates spaced 3.50 cm apart. The plates are charged to 13.50 nc. What is the magnitude of the electric field between the plates? 1.61E+05 N/C O 8.07E+04 N/C O 0.000282 N/C O 8.07 N/C
