7. Two square horizontal plates with 2.00 cm sides are separated by 5.00 mm, and are charged to create a downward electric eld of 250 N/C. An carbon nucleus (mass 2.00 X 10'26 kg, charge q = +6e) is red from the center of the lower plate at an angle of 320 to the horizontal and speed of 10.0 km/s. (a) Compare the strength of the gravitational to electric force on the nucleus. (b) Describe the trajectory of the nucleus. (0) Which plate does the nucleus strike, and where
