(A) B +Q, A Two conducting plates of area A are separated by a distance d, as shown above. The upper plate has a net charge of +Q and the lower plate has a net charge of -Q. Point P is located a distance s above the center of the lower plate and closer to the lower plate than the upper plate. Assume the plate dimensions are very large compared to d and all gravitational forces are negligible. (C -Q, A Which of the following indicates the direction of the electric field at point P and the reason it has that direction? (D St The electric field is in the +x direction because the charges are equal and opposite. X The electric field is in the -y direction because point P is farther from the positively charged X plate. The electric field is in the -y direction because electric fields point away from positive charge and toward negative charge. The electric field is in the +y direction because electric fields point away from negative charge and toward positive charge.

Can you help me understand why my answers were incorrect?

d A B +Q, A (C) -Q, A Two conducting plates of area A are separated by a distance d, as shown above. The upper plate has a net charge of +Q and the lower plate has a net charge of -Q. Point P is located a distance s above the center of the lower plate and closer to the lower plate than the upper plate. Assume the plate dimensions are very large compared to d and all gravitational forces are negligible. D SV Which of the following indicates the direction of the electric field at point P and the reason it has that direction? P y 1. X The electric field is in the +x direction because the charges are equal and opposite. The electric field is in the -y direction because point P is farther from the positively charged X plate. The electric field is in the -y direction because electric fields point away from positive charge and toward negative charge. The electric field is in the +y direction because electric fields point away from negative charge and toward positive charge.

A very small, isolated sphere with charge +Q exists in an empty region of space. A second very small sphere is moved from far away to a short distance from the first sphere The second sphere has a charge of +2.0 x 10 C. As it is moved closer to the first sphere at a constant speed, the second sphere passes through the circular equipotential lines due to the first sphere. Two of these lines are separated by a distance of 0.020 m and have potentials of 100 V and 150 V. What is the magnitude of the average force needed to move the second sphere between the two equipotential lines? A (B C D 1.5 x 10-5 N 5.0 x 10-6 N 1.0 x 10-7 N -9 2.0 x 10-⁹ N X
