Q1 The electric field inside a capacitor is shown at left.Which arrow best represents the electric field at the "x"?Q2: A long thin rod carries a uniform negative charge.Which arrow best represents the direction of the electric field at the observation location? Q4You stand at location A, a distance d from the origin, and hold a small charged ball. You find that the electric force on the ball is 0.009 N. You move to location B, a distance 2d from the origin, and find the electric force on the ball to be 0.0045 N. What object located at the origin mightbe the source of the field?1. A point charge2. A dipole3. A uniformly charged rod4. A uniformly charged ring5. A uniformly charged disk6. A capacitor7. A uniformly charged hollow sphere8. None of the aboveQ5:You stand at location A, a distance d from the origin, and hold a small charged ball. You find that the electric force on the ball is 0.08 N. You move to location B, a distance 2d from the origin, and find the electricforce on the ball to be 0.01 N. What object located at the origin might be the source of the field?1. A point charge2.
