An electric field with magnitude 500,000 N/C causes a point charge to hang at the angle 3 as shown in the figure below. If the charge has a mass of 2.00 g and a charge of +250 nC, what is the angle 6 [the figure is not to scale)? 3x915O 45 .O0 50.4'3 52.50 0/ 1}} Choose the correct statement concerning electric field lines: O At any point, the electric field is parallel to the tangent to a curved field line at that point. O Electric field lines are trajectories of a test charge. O None of these answers are correct. O At any point, the electric field lines are vectors in the direction of the electric field. O Electric field lines point away from negative charge.Estimate the magnitude of the uniform electric field required to "float" a proton near Earth's surface. Hint: . mass of a proton mp ~ 2 x 10 2 kg and charge of a proton 9p ~ +2 x 10- C' O E ~ 10 12 N/ C O E ~ 10 8 N/C O E ~ 2 x 10 20 N/C O E ~ 10 7 N/ C
